Sentinels are unique, bringing both tech and biotic abilities to the battlefield. They are versatile and always equipped to deal with any situation. After overloading an enemy shield, Sentinels have no trouble throwing the opponent with their biotic powers. Additionally when battles become too heated, they can Cryo Freeze an enemy buying the Sentinel precious time eliminate foes or take cover.

Sentinels are also equipped with the most advanced Tech Armor to keeping them safe in hostile situations. If overloaded, the system discharge and stun all enemies within a short distance.

Overview Edit

The Sentinel relies heavily upon tech and biotic powers both for offense and defense. The sentinel arguably has the most survivability out of any class due to its signature ability, Tech Armor, and its ability to quickly incapacitate dangerous enemies. The sentinel is the only class capable of disabling all three forms of defenses, armor and biotic barriers with warp, and shields with overload. Its class power of tech armor can double its shields and provide shock damage upon destruction. The main weakness of the sentinel is its lack of weapons training, in that it is able to use only heavy pistols, submachine guns and heavy weapons. All in all, the Sentinel is a versatile class that is capable of handling most situations, ranging from close quarters combat to long range, with its only notable weakness being heavily armored opponents.

Some of the differences between Mass Effect and Mass Effect 2 are that the sentinel has access to more weapons in the form of heavy weapons and SMGs. Also there are more powers and a reduced cooldown in the form of a global cooldown. Also the sentinel has access to a good defensive power in the form of the tech armor, which helps survivial. Overall the major differences are that the sentinal is more effective in combat in Mass Effect 2 than in Mass Effect.

Overal, due to their not being as proficient as an adept or an engineer in their respective fields, and lacking some advanced weapon training, the sentinel is considered by most a "jack of all trades, master of none".

Powers Edit

Class Powers Edit

Throw Edit

Main article: Throw

Throw uses mass effect fields to hurl targets away, damaging them if they hit an object. It can also be curved around objects and cover to hit its target. Throw really shines when used in conjunction with pull, which reduces a target's mass, and thus allows throw to launch foes against walls or over nearby ledges more forcefully. throw also has an instant kill possibility: a frozen target thrown at an object may shatter instantly. Combining this power with Cryo Blast makes this quite effective. On higher difficulties, throw loses some of its usefulness as it is only effective against unprotected enemies. It is still useful, however, for throwing enemies off of ledges once they have been stripped of their defenses.

Warp Edit

Main article: Warp

Unlocks with throw at level 2.

Warp spawns a mass effect field that damages enemy targets and stops health regeneration. Warp can be considered the bread and butter of the sentinel's biotic offense, perfectly reflecting the class as a whole, lots of applications, but with limited power. First, as mentioned, it stops health regeneration, making it very useful against krogan or vorcha. Second, it is potent against armor, although not to the degree of incinerate, and against biotic barriers. Lastly, if the target is affected by another biotic ability, such as reave, pull or even slam with precise timing, it will detonate the target, causing damage and knocking back enemies near the target. Warp is very useful on higher difficulties, where many enemies are protected by at least a thin layer of armor, and others have both armor and biotic barriers. It is notable that the warp explosion damages all enemies, even when they are protected.

Tech Armor Edit

Main article: Tech Armor

This power generates an energy armor suit that boosts the user's shields. Considering that most enemies will be much more attracted to the Commander than your squadmates, having a powerful, unique defensive power really gives the sentinel an edge on higher difficulties. Once activated, the armor remains active until it is destroyed or upon exiting a combat zone or loading a game. On occasions when it does get destroyed, tech armor sends out a pulse of energy, knocking back and damaging nearby enemies within a certain radius of the Commander. This reactive damage is very useful when facing melee enemies such as husks or varren, especially as they tend to swarm in large numbers.

Overload Edit

Main article: Overload

Unlocks with tech armor at level 2.

A very useful multi-purpose ability, it's also the other defense-disabling ability available to the sentinel. Overload focuses on shutting down enemy shields, damaging synthetics and from rank 3 onwards, overheats weapons. It can also be used on explosive canisters and flame-throwing enemies in order to make them combust and explode. Due to the tendency of enemies crowding close to each other, area overload is usually the better option in higher difficulties. Against synthetics, the stun effect and the weapon overheating can affect several enemies at once.

Cryo Blast Edit

Main article: Cryo Blast

Unlocks with overload at level 2.

When activated, this powers fires a mass of super-cooled subatomic particles capable of snap-freezing targets within a certain radius. Cryo blast is the only crowd control ability available to the sentinel, and it can curve over cover to hit its target. Because the enemy is unable to act during the cryo freeze, safe shots can be fired without fear of retaliation. Frozen enemies are also more susceptible to direct damage and can shatter when their health is low enough. However, any sort of armor, shielding, or barrier prevents the target from being affected, meaning this power loses some of its usefulness on higher difficulty levels. Also, frozen enemies have a tendency to fall behind cover, thus making it difficult to finish them off. Throw can be used instead to counter enemies such as krogan, varren, or husks who may be charging at you.

Defender Edit

Main article: Defender (power)

The class ability of the sentinel augments its most important attributes. Defender reduces the cooldown timer on powers, increases Shepard's health and gives a negotiation bonus by boosting Paragon and Renegade points. Both of Defender's evolved forms have advantages depending on play style. Aggressive sentinel players may prefer Guardian since Shepard can use powers more frequently, while those with a more "artillery" style of play might find Raider to be a better option.

Notable Bonus Powers Edit

Armor Piercing Ammo Edit

Main article: Armor Piercing Ammo

Becuase the sentinel lacks any ammor power, selecting Armor Piercing Ammo might be a good idea. It can do damage against armor and health, it would be a good selection. Espeically becuase the setinel has access to powers that can take down barriers and armor, but another weapon power would just be serving that purpose. Becuase armor piercing ammo can damage health and armor, it is a good selection choice.

Shredder Ammo Edit

Main article: Shredder Ammo

Becuase of the sentinel's ability to quickly deal with armor and barriers, selecting a passive weapon power that can shread enemy's health bar, can be a good choice. Sentinels are good at providing cover and destroying defenses, a weapon power that can also damage health, would also be a good weapon choice.

Reave Edit

Main article: Reave

Reave is a very useful bonus power, as it is effective against barriers, armor, and health, and it also stuns unprotected organics while giving a bonus to health regeneration. While reave may seem somewhat redundant due to the sentinel's access to warp, but it also has some other bonuses. Choosing this power comes down more to your play style than anything else.

Geth Shield Boost Edit

Main article: Geth Shield Boost

Of the three defensive powers, geth shield boost is the tech variant and can benefit from the setinel's natural tech abilities. However this power is kind of redundent becuase of the setinel's class ability of tech armor, but it can still be useful in heavy combat situation, or on higher difficutly levels. Due note however that when these Powers are used in conjunction with tech armor, only tech armor will have a visible effect. Also note that these powers DO have a time limit, so when restoring your shields to full, make sure to activate your bonus power rather than Tech Armor.

Barrier Edit

Main article: Barrier

Of the three defensive powers, barrier is the biotic variant and can benefit from teh sentinel's natural biotic abilities. However this power is also kind of redundent becuase of the tech armor ability, but it can provide a boost to your shields if you are in a heavy combat situation. Due note however that when these Powers are used in conjunction with tech armor, only tech armor will have a visible effect. Also note that these powers DO have a time limit, so when restoring your shields to full, make sure to activate your bonus power rather than Tech Armor.

Energy Drain Edit

Main article: Energy Drain

While the Sentinel already possesses a means with which to disable shields overload, the energy drain power allows a sentinel to restore a portion of the enemy's shield to their own. This can be very useful coupled with tech armor, allowing the sentinel to recharge some of their shield instantly without having to rely on a defensive skill with lengthy cooldown.

Flashbang Grenade Edit

Main article: Flashbang Grenade

The flashbang grenade combos well with the sentinel's robust shield-breaking to give an option to shut down packs of enemies pre-emptively, as it works against enemies protected by armor and barriers/shields. The power is just another one of the ways that a sentinel can control the battlefield and disable enemies. In addition, because it is a tech type power, it benefits from a sentinel's class power.

Weapons and Equipment Edit

Weapons Edit

Heavy Pistols Edit

Main article: Heavy Pistols

Becuase you only had access to pistols in Mass Effect, these weapons will seem very familier. Pistols are good weapons at mid to close-range combat, and considering you have access to two different weapons, picking between the two will be more dependent on what other weapons you have, what you will be encoutnering, and where you are going for you missions and assignments. There are only two pistols, but with the Firepower Pack comes a third, the M-5 Phalanx. The Phalanx is a good weapon that is powerful in close-range, and is accurate in mid-range as well. Any of the three pistols are good and probably switched out based on the mission you are about to undertake.

Submachine Guns Edit

Main article: Submachine Guns

In Mass Effect 2, the SMG adds a huge bonus to the amout of damage that the sentinel can do, and improves the ability of the sentinel to provide cover and protect their squadmates. Becuase you will probably be using SMGs more than your pistols, it is recommended that you try and upgrade the M-4 Shuriken as quickly as possible. This means either doing Tali's recruitment mission, or if you have the Kasumi - Stolen Memory DLC pack, doing Kasumi's loyalty mission, should be a top priority.

Heavy Weapons Edit

Main article: Heavy Weapons

M-100 Grenade Launcher Edit

Main article: M-100 Grenade Launcher

The M-100 Grenade Launcher is the first heavy weapon to be acquired during the Prologue: Awakening mission. The weapon is good against groups of enemies and for knocking back single enemies. The weapon does have a slight arc to it, but it is quick to adapt to. However, the M-100 may not be the best weapon on longer missions because of its limited ammo capacity. Overall the M-100 is a good all around weapon that will fit many situations and will work when no other heavy weapon will fit.

ML-77 Missile Launcher Edit

Main article: ML-77 Missile Launcher

The ML-77 missile launcher is a good all around weapon that has the added bonus of being able to lock on to enemies and track them. The ML-77 is a good weapon, while lacking the knockdown power of other heavy weapons, the ability to track enemies can outweigh that at times. The ML-77 has a high ammo capacity, which makes it very useful on longer missions and assignments, but because the projectiles don't do as much damage as other heavy weapons, you will use more ammo. Overall, like the M-100, the ML-77 is a good weapon that will also work in just about any situation and if no other heavy weapon will fit.

M-622 Avalanche Edit

Main article: M-622 Avalanche

The M-622 Avalanche is a good weapon on lower difficulties when enemies don't have protection like armor, shields, and barriers. This weapon also works great against Husks on lower difficulties as well because it can insta-kill them. However on higher difficulties the M-622 losses it effectiveness very quickly. Because enemies have protection, it reduces the chance of freezing enemies. This weapon is also mitigate by the sentinel's cryo blast ability, which is the M-622, just smaller. Overall because of the sentinel's access to the cryo blast ability, this weapon does have some limited usefulness to the sentinel.

M-920 Cain Edit

Main article: M-920 Cain

The M-920 Cain is a powerful weapon to say the least, but unless the weapon has 100% ammo or more, the weapon will not fire. At most you can use the Cain twice during a mission, usually once, so either plan for that, or leave the Cain in the rack. The Cain is powerful, and can destroy enemies, or at least damage them, in a large radius. However since the weapon can only be fired with 100% ammo, either plan to the weapon only once, or leave it behind.

Collector Particle Beam Edit

Main article: Collector Particle Beam

Acquired during the mission to Horizon, this can be a good weapon for a sentinel. While you don't need its ability to rip through the protection that most enemies have, it is still none the less a good weapon if you need long range support. Because the sentinel has access to powers that can disable shields, overload, and deal with armor and barriers, warp, this weapon which can rip right through them does seem to just add to that. However the weapon is great at range and it does have the ammo for a long mission.

M-451 Firestorm Edit

Main article: M-451 Firestorm

The Firestorm, or flamethrower, is an excellent weapon for the sentinel who prefers getting up close and personal with their enemies. Because the sentinel has access to tech armor, a powerful defensive ability, getting up close isn't as much of a problem. Also because the sentinel lacks a close range weapon, the M-451 might be a good option to fill that close-range slot.

M-490 Blackstorm Edit

Main article: M-490 Blackstorm

The Blackstorm is a good weapon if you need some crowd control abilities, and if you aren't going to select any squadmates with them. The singularity produced by the weapon has many uses including throwing enemies into the air, pulling enemies out of cover, and for tying up multiple enemies. Because the sentinel lacks any form of crowed control abilities, it helps fill in that role. The weapon does have a low ammo capacity, but it is a good weapon for those situations where crowd control is needed.

Arc Projector Edit

Main article: Arc Projector

The Arc Projector is almost a redundant weapon for the sentinel because of the overload ability. The Arc Projector however shines against synthetic enemies like the geth. Even with overload, this weapon can come in handy against multiple synthetic enemies, or when a lot of enemies you are have shields. The Arc Projector has a moderate ammo capacity, which makes it ideal for longer missions, but for the sentinel, it serves a limited purpose.

Advanced Weapons Training Edit

During the mission aboard the Collector Cruiser, there will be the option of training in the usage of assault rifles, shotguns, or sniper rifles.

Assault Rifles Edit

Main article: Assault Rifles

Assault rifles deal high damage at mid-ranges, and are a good all-around choice for any character, including a sentinel. Because sentinels lack any ability to effectively engage at mid to far-range, assault rifles would help the sentinel provide cover for their squadmates. Any of the two, three if you play on hardcore or insanity, or four if you have the Collector's Edition, would be a good addition to the sentinel's arsenal. A fifth assault rifle is added with the Firepower pack, the M-96 Mattock. The Mattock is a semi-auto rifle, which works like the pistols that you should be familiar with. However it works at longer distances, is more accurate, and does damage.

Shotguns Edit

Main article: Shotguns

Shotguns can synergize with Tech Armor, especially the assault armor variant, which makes it easier for a sentinel to approach enemies within an effective range, knocking them down and leaving them open to a point-blank shotgun blast. In the higher difficulties, however, this is not a viable option. Without the soldier's Adrenaline Rush or the vanguard's Charge, the sentinel will be hard pressed when trying to retreat from a CQC. However shotguns would be a good third weapon system because the sentinel is good at mid-range combat, so shotguns are still a viable option. The two DLC shotguns, the M-22 Eviscerator and the Geth Plasma Shotgun, are both more effective at mid-range, and the Plasma Shotgun is very powerful. Both weapons do a lot of damage, and because the sentinel does have access to defensive powers, picking up these guns may be a good choice.

Sniper Rifles Edit

Main article: Sniper Rifles

Sniper rifles are perhaps the best complement to the sentinel's existing abilities, offering the ability to kill enemies beyond the range at which powers can normally lock on. You can extend that distance while using the sniper zoom, and also providing excellent damage versus armor with the AP sniper rifle upgrade. A sentinel with a sniper rifle can deal with any enemy, anywhere on the battlefield. On the downside, it might seem a bit awkward when using powers while equipped with a sniper rifle, for the visual is locked into the rifle zoom while the power bolt travels to its target. The Aegis Pack adds the M-29 Incisor, which is good against shields. However with the sentinel's already healthy access to protection destroying powers, the Incisor may still be a good choice. Still sniper rifles would be a good choice for those sentinels who wish to keep their distance.

Combat Guide Edit

Combat with a sentinel is about debuffing enemies and providing fire support to squadmates. The sentinel has access to powers than can disable every type of enemy defenses and even do further damage to synthetics. The sentinel also has access to the tech armor power, which helps in close quarters combat by strengthing the sentinel's shields and providing another layer of defense. Using the sentinel's powers helps to make enemies easier to take down and to keep them at a distance. The sentinel’s only crowd control ability, throw, should be used in the respect of keeping enemies in a distance. It can also be used to throw enemies off a bridge, railings, and well anything else.

Because the sentinel has access to only three weapon systems, SMGs, Heavy Pistols, and Heavy Weapons, a sentinel needs to stay a little closer to the action. Using the tech armor ability, this is quite easy. The first priority for a sentinel should be getting an upgrade for their SMG, this means doing either Tali's recruitment mission or Kasumi's loyaly mission. Use the sentinel's weapons to provide cover and when necessary, attack. The sentinel may lack a little in weaponry, but makes up for it in the ability to rip through the enemy's defenses.

Squad Members Edit

Sentinels are effective against all types of defense (armor, barrier, and shields). This affords characters of this class a great deal of flexibility in selecting their squadmates. Any combination of team members can be chosen without exposing the squad to any particular weakness, and the most effective teams are usually tailored to fight a specific type of enemy.

However the sentinel lacks any effective combat skills, so bringing along a character that has access to an assault rifle, or a sniper rifle is a good idea. Mainly the sentinel needs access to a mid-to-long range shooter for backup. However the person wielding these weapons should be tailored to the specific enemies that you will be facing. This is primarily because the sentinel is adept at taking down barriers, shields, and armor, so you will need to pick combat squadmates based on their other talents and what they have to offer. Thane, with warp and a sniper rifle, is a good complement if you can find a spot for him to hang back and snipe. Better still are Garrus, with Concussive Shot and overload, and both assault rifle and sniper rifle; or Grunt, with researchable 50% health bonus, health regen via Krogan Berserker, and assault rifle. The best might be Zaeed, with a 50% bonus weapon damage, assault rifle and sniper rifle. Legion, to some extent, is also useful for it is the only squad mate capable of using the M-98 Widow after upgrade.

Because sentinels initially lack any ammo powers of their own; therefore, it's usually a good idea to bring along someone with a squad ammo ability to empower the entire team. Like the sentinel class itself, Jack's Warp Ammo may be a good choice as it is effective against both Biotic Barriers and Armor. Zaeed's Disruptor Ammo ability is effectively overload as an ammo power, and when evolved into squad ammo it can make the whole team more effective against shields and synthetic enemies. The disruptor ammo may be a life-safer when facing enemies like Geth Hunters and Geth Primes. The Shredder Ammo from Thane is effective against unprotected organics, but loses its effectiveness in higher difficulties where nearly every enemy is protected. The Incendiary Ammo power from either Jacob or Grunt is better suited to most situations for it provides bonus against armor, stops health regeneration and panicking organics when their protection has been stripped away.

The team's tech specialists, Legion and Tali should not be overlooked either. With their AI Hacking and Combat Drone powers, they can often damage enemies while effectively drawing fire away from the squad. Legion, armed with an assault and sniper rifle, should be selected for his superior weapon damage, while Tali may be preferred against synthetic enemies for her Energy Drain, which effectively mimics overload. A word of caution: both Tali and Legion are not strong in the health department and may fall quickly if the enemies focus assault on them.
