Having previously added Crowd Control support and a randomizer to UT99, TheAstropath decided to port the mutators over to Unreal Tournament 2004! As of today, Crowd Control now has public support for UT2004 and streamers can let their viewers influence the game in a variety of ways!
TheAstropath also made a randomizer that has a number of options from simply shuffling existing items around the level, to entirely changing what weapons and ammo are available.
If you don't stream, the pack also includes a "Simulated Crowd Control" mutator which will occasionally pick a random effect and apply it to your game, giving you the general flavour without needing to actually stream online (or have viewers, etc).
These various mutators work both in Instant Action games, as well as multiplayer games, so you can even share the pain with friends!
