Valve's inviting Team Fortress 2 players to beta test the game's new AI bots, which can be added via the in-game console.
To add bots to the game, players should simply use the command 'tf_bot_add', which will drop a random bot onto a random team (assuming there is a free player slot).
"Typing tf_bot_add pyro blue will add a Pyro to the blue team. Entering tf_bot_add red 5 will add 5 random bots to the red team. The command tf_bot_add red 3 heavyweapons will add three heavies to the red team," Valve explains.
"Since this is a beta test, the TFBots are only functional on these King of the Hill maps: koth_viaduct, koth_sawmill, and koth_nucleus," it adds. "They don't understand the rules of multiple point capturing, cart pushing, or flag getting... yet. There's also no interface in the game to accessing them yet (we'll add one in an update shortly), so you'll need to access them manually."
Good news for loners. For more info read the Team Fortress 2 blog.
