Hi,

Are there any bot scripts I can use for my server? I get bored when Im alone :(

I heard hompy made an unfinished(?) bot script. Has anyone finished his script yet? I would love to know. Thanks.

No he didn't. No one finished the script.

I have successfully managed to locate an operational bot script composed of a decent AI. However, this script only implements bots that launch grenades at you when you are in close proximity. I still do hope that this may be of interest to you. (NOTE: I claim no ownership nor contribution to this PySnip script.)

Oh, no I wasn't the one who requested the bot script. I am extremely sorry for any misconception. :)
