Valve has followed through with its promise to bring bots to Left 4 Dead 2's Versus mode -- which was frantic enough before all the A.I.-controlled ghouls got added in. A recent patch added the functionality and made a few tweaks to the software development kit, which allows players to make awesome levels based on awesome Nintendo 64 games. Check out the full list of changes after the jump.

The Steam blog post announcing the patch's release promises that the changes will be integrated into the 360 version of the game via an upcoming title update.
