Q4Max adds many features and fixes to Quake 4, making it a much more enjoyable and complete game. For this reason, most servers running Quake 4 are running Q4Max.
These are the files needed to get bots running in Q4Max. *I did not made this, am only uploading to MODDB
INSTALLATION: Place the "q4max" folder in "D:\Program Files (x86)\Steam\steamapps\common\Quake 4" or whereever Quake 4 is installed.
After that make sure you set the min bot value in Multiplayer settings to be more than "0". Enjoy your bots.
