3 more levels from a master. One is simply a fun bit from a RED solo map, but all three are really playable - you'll spend most of your time getting blasted by friends, and very little time trying to figure out where to go next. Those RED weapons are just built for carnage, aren't they?
A square level, with a bunch of fake walls, and hundreds and hundreds and hundreds of rocket packs. Internally, the level is called 'Die', which is relatively accurate - you can't always see what's coming at you, because of the fake walls.
