Left for Dead 2 is an amazing game. Fun, replayable, mod compatible. Altho tbh, it's more fun with friends. Also, i'm pretty sure it comes with the first one, or so I think since it has levels from LFD1. If i have to mention a funny moment it would be that one time, I got a mod that added levels from Sonic 3D Blast for the survival mode, and there's no collision on the borders of Green Grove Zone Act 1. I saw how a Charger tackled Tails out of the map withouth being able to do anything.
