They're 'fake' client entities, traversing the level, and acting upon objectives they either figure out themselves, or are told to to act a certain way.
*We encourage any multiplayer game to support them*, because they often also fill in the function of balancing teams. There's a whole slew of benefits of supporting bots, and *players will generally thank you for including them*.
Nuclide's BotLib takes some inspiration from **Quake III Arena** its bots, but shares no code or specific ideas or implementations. We do not use **AAS** for navigation, we leverage the route/pathfinding system **FTEQW** provides. Bots also share some code with regular NPC/Monster type entities through the use of the ncActor class.
