Originally built in 2009 to test the pre-release Lua HUD engine. Demonstrates a rotating compass and a compact ammo display. Works with any scenario.
Now marathon's UI looks like a halo game! (Edit: I just tried out the hud and holy cow it's amazing, I like the compass that is around the radar. The UI, the health bar, and the ammo counter. Perfect, perfect, right down to most, tiniest details.)
