I know the real name is not cs_pacman, but this name is more descriptive.
This is a very unique map for CS:Source. I just played a few rounds with the bots, and it's great. It can get disorienting though.
Study the layout carefully before playing. If you played a lot of PacMan before, you probably won't get lost.
Relax! It's a small download this time.
Clicky!
