That should work, are you sure you are starting a team game (CTF, TFFA)?
A workaround is to:[list=1]
Make a New Text Document and rename it bot_teams1.cfg or whatever, as long as it is a .cfg file and it is in your base folder
Put this in the bot_teams1.cfg file:
set g_teamforcebalance 0
set bot_minplayers 0
addbot luke 5 BLUE
addbot kyle 5 BLUE
addbot jedi 5 BLUE
addbot jeditrainer 5 BLUE
addbot shadowtrooper 5 RED
addbot newreborn 5 RED
addbot rebornmaster 5 RED
addbot cultist 5 RED
addbot alora 5 RED
assuming you will be the 5th person on the blue team. Of course you can use different bots or a different number of bots as long as the total number of players is equal to or less than sv_maxclients. If the bots are "too good" set the skill level less than 5 (1-5).
Start the game with no bots, just make sure that you have enough player slots (set them to "Human").
In the console, enter /exec bot_teams1.cfg and the bots will be added
[/list=1]
You can have multiple files like that specifying different numbers\combinations\skill levels of bots.
BTW, if you are going to play against bots, I strongly recommend downloading the DDS I-bots and DDS improved botroutes available here (
