A map that I previously made, but forgot about. Completed shortly after my first two, vent is set in a missile silo control bunker. There are several secrets to this map, but it is pretty simple. All weapons are included, although a couple may be a bit hard to get to. I'd say 4-6 players would be about right for this map.
Keep in mind I completed this a long time ago, and just recently refound it. Comments, etc are welcome. I am in the process of starting a new hl2dm map that I hope will be released by the end of the year (yeah, I'm slow).
Additionally, I'd like to thank Mastermind for the Silo prefab. I just found the reference to credit!
