Just released this a few days ago:
viewtopic.php?f=3&t=35329A L4D2 Survival map. Took about a month. You can read more about it on the fourm.
Some of you may remember a post I made a while back about "Hotel Fight" a HL2 EP2 mod I was working on. My HDD crashed and I lost a good few months of work on it. I salvaged the first map, but that's about all. I'll finish it sometime in the near future. I have to re-do all the damn lighting.
