Run UT2003, and from the Mutators list select Light Suit Mutator, then select a map to play on.
2. Light Suit.. is it a suit which makes light?
Indeed it is! How did you guess? ;-)
The Light Suit mutator gives you the option to toggle an ambient light around you on and off. You can use it to light up dark areas and clash lighting colour schemes!
In the Options - Controls menu you can find a key that you can set to toggle the light on and off when you are running the mutator. Under the Mutator Configuration menu, you can also specify the colour, hue, radius and brightness of your suit light. (New for UT2004)
3. Known bugs
A few, yes:
* You need Dynamic Lighting enabled to see the light. If anyone knows a way around this, please let me know!
* It might drag your frame-rates down, but there's not much I can do about this.
* It won't work with mutators or mods that use custom controller classes. I think a mutator like MatrixMoves is a good example.
