It's operated by a computer, which is hooked up to the turret via an option in the computer's class when added into the levels. After successful connection, you get to the window for controlling the turret.
The window has:
- A viewport from the turret's POV.
- Aforementioned viewport has toggleable readouts on ammunition and target data.
- Viewport also features a targeting reticle that works in the same way as the default IFF system (Enemy = red, friendly = green, though scripted pawns are always yellow to the reticle.)
- Manual and automatic firing. Automatic operates from a button on the window, manual is operated by pressing/releasing Left Mouse button.
- The gun fires self-targeting rockets.
- The gun has finite ammunition, and is reloaded by collecting special ammo classes, and pushing the 'Reload Gun' button on the computer window.
- The viewport has some rudimentary Vision Enhancement, that drains the player's Bio-electric energy.
- The gun goes mad if hit by EMP, like a standard turret.
- It's just f**king cool.

The gun works perfect in SP, but I'm wrestling with replication in MP. The gun can connect, but doesn't move. -_-
Just thought I'd let y'all know.
