lol Wake, I feel sorry for the poor newbie that types in THAT command.
Time for Mr. Desktop. The new improved version of alt-f4
EDIT- Reason why it doe scrash, was because the devs originally DID put a model (I believe it was a different version of those "crabs" in singleplayer) but later was removed. However, the model command was still in the files. Once you type it in, the game crashes due to a "model not found" error, or something along those lines. Just lazy developers, or forgot to remove it.
Current in-game name is #include
