Alien Vendetta Map25 imo my first and fav slaughter type map. The concept is just really cool, It is an huge wave of demons invading a town. The longer it is the more bs and difficult the segments are. The music fits incredibly well, it's hopeless, bleak, the situation is so heavy and everytime you're under pressured but you just need to do it, you need to stop this chaos at all cost. The map is known for incredibly long and is one of the 2nd hardest map in the wad (i think).
