Forerunner automated turret

The Automated Turret is a form of equipment similar to an immobile Sentinel that acts as an automatic defense system (deployable antipersonnel turret) for the player and first featured in Halo 3. It is so far only encountered on the Halo 3 levels The Ark, The Covenant and Halo. It is not found on any multiplayer maps. The auto-turret is dropped in an area where you want to defend. Once deployed, it will automatically shoot at the enemy.

Function
This small robotic turret is Forerunner technology found on the Ark and resembles a stripped down Sentinel. It fires a thin, blue beam at enemies. This device is extremely adept destroying Flood of all kinds, although it can be used to kill Covenant forces as well, however it takes quite a long time to find and shoot a target. It is extremely powerful and will kill a fully-armored Brute in two shots. Technically it can be considered as a type of Sentinel.

Its HUD symbol is a silhouette of the contraption itself and vaguely resembles the symbol for the Power Drain.

Disadvantages

 * Due to programming issues, the turret has major problems picking out targets and more often follows allies with its targeting system.


 * Also, upon the betrayal of 343 Guilty Spark in the level Halo, all Sentinels, including the Automated Turret, will fire upon you. Players should remember that before you enter the Control Room on the level Halo any Automated Turrets should be destroyed as they might possibly kill you once you get within range after you activated the Ark.


 * The turret is also easily deflected. Even the slightest touch can move the turret away from the enemy, facing you.


 * Sometimes during The Ark, the auto turret will fire upon you and in other levels it may also fire at you for no reason.


 * Between its poor targeting and low health, the Automated Turret often provides few kills without considerable player support.

Trivia

 * This piece of equipment is unavailable in matchmaking.
 * If these turrets are deployed after the destruction of 343 Guilty Spark in the level Halo and survive, they will attack you, killing you in one sustained hit, or even two very short hits (the first takes out the shields and the second kills) even on Easy difficulty. (a good move is to destroy them if they survive)
 * On The Covenant, during the part where the Flood ally with you, the turret will shoot at the Flood and vice-versa.
 * The Auto-Turret can help you score campaign metagame-points, although this sort of information is yet unknown.
 * The Auto-Turret has an odd tendency to "bounce" when a player runs into it, and even more interesting, when it lands it seems as if it just falls on an invisible platform, rather than float loosely back into its position.
 * Auto Turrets are basically a Sentinel-like robot with unintelligent AI and lowered movement capabilities so it will attack you if you try to use it on 343 Guilty Spark since he controls most of the equipment on the replacement Installation 04.
