Named in memory of the quarians killed in the Morning War on the planet Adas, this weapon's electrical attack has been optimized for medium- to long-range firefights. Alliance marines take issue with calling it a "rifle" since, technically, it has no rifling in its barrel. The quarians shrug this off, as quarian weapon terminology rarely translates flawlessly into human languages.
The Adas Anti-Synthetic Rifle is a powerful weapon that fires rounds that inflict splash damage against enemies, making it useful for crowd control. Whole squads can be suppressed due to the knock-back effect. The rounds also appear to have a slight target-tracking capability, allowing for easier aiming.
As its name implies, the Adas Rifle is devastating against synthetic enemies like the geth, Turrets, and Atlas mechs. It is also effective against Cerberus and Reaper enemies, especially Ravagers because it can knock out the Swarmers they spawn with its splash damage.
The Adas is a poor choice for sniping due to its homing ability, which often results in shots hitting cover instead of the enemy when aiming for exposed points. This can work the other way however, aiming in the correct place will allow the user to shoot around/over cover.
The only other significant drawback to this weapon is its ammunition consumption. The rapid fire and full-auto capability cause the Adas to burn through clips quickly.
The Adas's extra damage against synthetics makes Disruptor Ammo somewhat redundant.
Due to the nature that squad members have no ammo count restrictions, consider equipping them with Adas rifle in missions that has multiple encounters with enemies like Brute and Banshee, even normal Husk - against enemies that negate the use of cover, attempt to use the strength in numbers and/or native defense are times that Adas can truly shine.
