CheatsCW + Networking Multiplayer question

[LunaMoo]

Not true, in fact it's made up bs. It's more than possible to run cheats in multiplayer althrough many simple cheats sucks and typically work only in one specific game mode which most of the time is singleplayer.
FPS patches can also be used with multiplayer however in that case, most of the time all players will have to use same cheat. Not always required but running the game at different fps this will cause desync problems leading to disconnect or other player seeing you faster or moving weirdly teleporting around, that really all depends on game.
