Player Notes

 * The Sentry Turret is deployed as a grenade, being thrown from the player prior to deploying. As such, it can be slightly difficult to position, though there are instances where this can work to the players advantage, such as allowing deployment of the turret around corners.
 * Unlike the Combat Drone, the Sentry Turret is stationary, making it ideal for covering your flank. Upgrading it with the Flamethrower at Rank 6 allows it to be an effective close quarters weapon. The Rocket Upgrade will allow to do more damage at longer ranges.
 * In addition to the turret's obvious destructive potential, the turret can also serve as a distraction, similar to the ability Decoy (though not nearly as effective). Sometimes the enemies will focus on the turret and leave you alone until the turret is destroyed or another threat becomes more obvious and dangerous.

Availability

 * Single-player: Engineer
 * Multiplayer: Quarian Engineer
