Everytime you run QuakeWorld, there's the option to play by yourself, practice movement or aim, alone or against bots.
Bots replace human players. You can spawn bots in compatible KTX servers. See more Playing with bots.
But also offline. See below.
Team deathmatch, FFA
You can also play with bots offline.
pop the folder in your main Quake directory, boot up the game and use the following:
