Quake 3 vstr Rotation with Custom Bots
Solution 1:
What you need to do is to edit your server config file to automatically add bots to fill up empty slots:
bot_minplayers [number] - Sets the number of minimum slots that will be filled by bots.
If you do not have enough players to exceed that minimum per team, it'll fill the rest of the slots up with bots.
To specify particular bots or add custom bots for your server, you'll have to modify your bots.txt file
