ttt_bioresearch_v1 Fun, medium sized map that takes place in a research facility of sorts. Plenty of places to hide things like bodies, c4, or health/death stations if you are of the sneaky sort. There is some framerate drop, but only in one room that I noticed when you blow up a series of barrels that sets fire to all the props in the room. http://steamcommunity.com/sharedfiles/filedetails/?id=246329964 ttt_manufactory Medium sized, open map with plenty of places to snipe from although it will be from ground level. There are several buildings to enter and play around in and a big outside area. A few hiding spots here and there for the sneaky traitor. http://steamcommunity.com/sharedfiles/filedetails/?id=246369972
