tag_airsoftfort is an fy style map with an objective other than "kill the other team". It has 4 hostages that spawn inside of their own rescue zones. This means that all a CT must do is "tag" them out to rescue them. The airsoft theme is kept up not only with the thin wooden buildings but also by everyone being equipped with an MP5 (with a few shotgun pickups laying around) so that there is no bullet penetration. The counter-terrorists can spawn on either side of the map meaning terrorists must prepare for an attack from both sides.
de_airsoftfort is simply a bomb defuse version of tag_airsoft fort. T and CT spawns are swapped, hostages have been removed, and two bombsites have been placed in the two upper buildings that do not have stairways. Players are also equipped with kevlar on this version.
Both the maps in this download have an _nw suffix, standing for "no wad" because some servers were having issues downloading the small custom wad that came with the original maps. I recompiled a version of each map with the textures from the troublesome wad file embedded into the bsp.
