Player Notes Edit

  • Firebase Rio has the largest number of ammo dumps (with increased amounts of grenades) spread across the entire map than any other multiplayer map. Grenade-based characters will do well on this map and will find restocking grenade supply easily accomplished.
Grenade Resupply Location Bronze Silver Gold Platinum
Armored Core (Left) 4 2 2 2
Armored Core (Right) 4 2 2 2
Central Tower (East Bridge) 2 1 1 1
Central Tower (West Bridge) 2 1 1 1
Loading Dock (Small Door) 6 3 3 3
Loading Dock (Large Door) 6 3 3 3
Relay Station (Center) 4 2 2 2
Relay Station (Railing) 4 2 2 2
  • The Central Tower makes for a great sniper nest. Not only do you have a good open view down both sides but there are two ammo crates very close by, so weapons like the M-98 Widow with low ammo capacity can be stocked easily.
    • For the same reasons the Central Tower is good for grenade-using characters like the N7 Demolisher Engineer.
    • Note, however, that much of the cover in the tower is positioned in such a way that being protected from your front exposes your rear. Be aware of potential attacks from behind.
  • The Loading Dock is a strong defensive location. It has ammo, plenty of cover, and long sightlines on the ramps leading from the Control Tower.
    • At the back of the Loading Dock is a container with large doorway and an ammo box inside. Players are immune to most instant-kill attacks while inside this container, since most enemies capable of such attacks are too large to enter the container themselves (the Phantom being a notable exception) and the floor of the container is slightly elevated from the ground. This makes for a useful "panic room" on higher difficulties, when enemies capable of instant kills spawn in large numbers.
