Forerunner automated turret

The Automated Turret (also known as the Auto-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 a piece of 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 at 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.

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. It can also sometimes fire at the Master Chief or Arbiter by accident. It usually can kill you in one or two shots, depending on difficulty.


 * 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 surviving Automated Turrets should be destroyed as they might possibly kill you once you return to their location after activating Installation 04 (II), quite often killing you before you can destroy them.


 * The turret is also easily deflected. Even the slightest touch can move the turret away from the enemy, facing you, or send it flying into the air.


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

Trivia

 * This piece of equipment is unavailable in matchmaking and multiplayer.
 * On the mission The Covenant, during the part when 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, as it was deployed by you and not meant to be a permenant ally.
 * As said above, the Automated Turret is of Forerunner-make, so once 343 Guilty Spark finalizes his betrayal the Sentinels and everything under the Monitor's dominion will kill the Master Chief and the Arbiter, including the turret.
