Guaranteed round 100 in about 10 minutes. Take the already modded gamesave you have (if you don't have it google for it, I don't have it either) open it up in hex workshop or something, and after all the other modded strings insert " g_spawnai "0" " Resign and rehash, put onto your harddrive (inject sounds too medical or gangsta) and hit resume game. Timescale 10 for best results. Have fun. BTW, die by holding a nade, in case you forgot.
