Wow. This one isn't new... again, it's a 1997 Conahan production that never made it into the archives... but wow. It's a training package... bobs are replaced with (damn good) pistol shooting marines, troopers are replaced with shotgun-toting marines, and cyborgs are replaced with missile-shooting marines. These guys are GOOD. You wanna practice, but have no net access? Download this. Comes with one of Mark's maps, and some textures that go with it. (Warning: it's very, very hard to stay alive. Find the rechargers, first off.)
