Player Notes[]

Mechanics
  • The Sentry Turret's normal attack fires in a burst of three shots with a burst every 2.5 seconds.[1]
    • However rare, the Sentry Turret's normal attack can actually headshot enemies.
    • The Cryo Ammo/Armor-Piercing Ammo evolutions at Rank 5 only influence the normal 3 round burst attack and have no impact on any of the alternate weapons such as shock/flamethrower/rockets.
  • The Rank 4/6 shock/flamethrower/rocket evolutions do not replace the Sentry Turret's three round burst attack, nor will they remove other similar evolutions. These evolutions simply give the turret additional functions.
    • The Sentry Turret will randomly select between all available weapons for a given target in range. This has the consequences that taking both the shock and flamethrower evolutions can actually reduce the turret's close-quarters damage potential, as the turret will then be randomly choosing between the highly-damaging flamethrower or the less-damaging shock attack.[2]
  • The Rank 4 Shock evolution is almost identical to the Combat Drone's, dealing 100 base damage,[3] for a net total of 130 with the mandatory Rank 3 evolution. It also has the same radius (2.5m single-player, 5m multiplayer) and force (450N single player or 1000N multiplayer, which is capable of staggering moderate enemies in single-player and all but the hardiest of enemies in multiplayer). In single-player, The Sentry Turret has an identical attack cooldown (5 seconds), though in multiplayer it is faster (2 seconds versus 3 seconds for the Combat Drone's).[4]
  • Sentry Turret is deployed like a grenade, unlike the Combat Drone which simply appears on top of whatever enemy you are targeting.
    • Sentry Turret, once deployed, will not move.
  • Rank 5 Cryo Ammo can freeze unprotected enemies, making it the only way that Sentry Turret can create Power Combos. The Rank 6 Flamethrower evolution can light affected enemies on fire and it may seem like this is priming them for Fire Explosions, but it is NOT a combo priming effect, merely damage over time.
  • Despite Sentry Turret being a tech power, Sabotage's Rank 6 Tech Vulnerability only affects the damage from the Rank 4 Shock evolution.
  • The Rank 4 Shields & Damage evolution also influences the damage done by the weapons given at the Rank 6 evolutions: the Flamethrower damage per second increases to 93.50 (110.50 multiplayer) and the Rocket damage increases to 195 (510 multiplayer).
  • The Sentry Turret can block your own gunfire. Never try to shoot through it or past it.
  • Certain enemy projectiles seem to either have a hard time directly hitting Sentry Turrets or are totally incapable of harming them directly, though indirect splash damage from hitting nearby targets or terrain will still hurt them. These projectiles include the warp-like projectiles launched by Banshees, and the cannon fire of both Harvesters and Ravagers. This can make the Sentry an especially useful decoy against those foes, though it should be noted that Ravagers totally ignore both Sentry Turrets and Combat Drones.
Strategies
  • Sentry does significantly more damage to enemies in multiplayer. On higher difficulties in single-player, Sentry is most useful for drawing enemy fire away from the player and for its various "crowd control" effects: freezes, shock stuns, and the panic effect that can be induced by the Flamethrower evolution. It is also a useful "bug zapper" in fights against Ravagers to clean up Swarmers, especially since Ravagers totally ignore Turrets and Combat Drones.
  • One of the interesting characteristics of the Sentry Turret (like the Geth Turret) is that it "knows" where enemies have spawned at the beginning of a wave in multiplayer (or if stragglers are left over that you can't seem to find). A few seconds after the wave spawns, the Sentry Turret will turn to the direction of the spawned enemies and begin firing. This can be very useful on large maps or maps with lots of obstructions/cover to see where enemies are going to be approaching from and to be able to take appropriate actions. Firebase Reactor is a good example.
  • Due to the fact that you "throw" the Sentry Turret to position it, you can use this to your advantage, such as allowing deployment of the turret around corners.
  • Because the Sentry Turret is stationary, it can be ideal for covering your flank. Upgrading it with the Flamethrower at Rank 6 allows it to be an effective close quarters weapon. The Rockets evolution will allow it to do more damage at longer ranges.
  • In addition to the Sentry Turret's obvious destructive potential, the Sentry Turret can also serve as a distraction, similar to the power Decoy (though not nearly as effective). Sometimes the enemies will focus on the Sentry Turret and leave you alone until the Sentry Turret is destroyed or another threat becomes more obvious and dangerous.
  • The Sentry Turret will still target cloaked Cerberus Phantoms and Geth Hunters. The flamethrower evolution is more suited to taking them out, since the Sentry Turret will target anything that enters its radius.
