Change Bot #
In the Crave\GlobalOperations\GlobalOps\attributes folder, there is a file called "singleplayer". If any of the levels are giving you a really hard time, you can edit this text file.
The file is in plain english and is where the number of bots is picked from. Most levels have 1 of each type of player: medic, commando etc. You will see a name of the character followed by a 1 or 0 (0 being "good guy" and 1 being "bad guy").
In the first round of play, you are a good guy -- in the "next" round of play -- your a bad guy.
Modify this file as desired and save. Always make a backup before overwriting the file.
