Very decent and can also replace the broken co-op game: Synergy.

All though it will cause bugs when random add-ons are installed like for instance player models causing the game to crash.
Or other problems, It's still sad to see servers die out on gmod like for instance, Most servers are now nothing but DarkRP and other ♥♥♥♥, But otherwise still a good game.
