Turrets

Turrets are immobile weapons platforms that can be controlled by players or autonomously fire at opponents. Some can be entered like vehicles, but are much more limited in their movement.

Unreal Tournament

UT features two types of automatic turrets in some Assault maps. Both can be neither controlled by players nor destroyed through weapon fire. They do shut down for some time after taking more than 220 points of damage, though.

• 

  Ceiling Cannon
  
  Ceiling-mounted, fires projectiles; projectile type and damage depend on the map

• 

  Minigun Turret
  
  Floor-mounted, rapid-fire trace-hit

The map AS-Overlord features a mortar. That's basically just a fixed-direction projectile spawner, not a "real" turret, though.

The Game of the Year (GOTY) edition of UT also comes with the mod Chaos UT, which features a deployable automatic turret firing rockets and shock balls.

XMP

XMP features the following turrets, all with 600 health. Turrets aren't entered, but controlled from computer screens in its vicinity. Like vehicles, turrets are extra sensitive to EMP damage. One of the turrets can move on a rail, a feature that returns for UT3's turrets. All of the turrets must be manned and take energy from the team's reserves. (The turrets aren't officially named in the actual game, but appear like that in the code.)

• Roundhouse Turret - Fires red plasma
• Turret Post - Fires red plasma
• Winged Turret - Fires plasma
• Garden Turret - Fires green, very fast bullets
• Turret Giant - Fires mortar shells
• Lowlands Giant Cannon - Fires electrical discharge with a delay, somewhat similar to the Ion Cannon of UT2004

Unreal 2 and XMP also feature deployable "Auto Turrets" and "Rocket Turrets" that function independently of the players.

Unreal Tournament 2004

UT2004 features a number of different turrets, which can be healed with the Link Gun. The following list shows the default health for each turrets. (Different maps may features turrets with more/less hitpoints if so programmed.)

Default Onslaught maps feature only Energy Turrets, whereas Assault maps feature the other types.

When a player is in an Onslaught Energy Turret, it appears as headless or, more accurately, having a special helmet on.

  Usually protects the teams' spawn points. Shoots lasers. AI-controlled. Can be floor- or ceiling- mounted. Used in AS-Mothership as a destroyable objective.

Unreal Tournament 3

Turrets in Unreal Tournament 3 have a default health of 400 and are usually mounted on rails to provide limited movement. All turrets have a zoom function as their secondary fire mode.
