Aliens vs Predator 2 singleplayer custom map titled "Primaeval".
Map author: Phil 'Windebieste' Wlodarczyk
Primaeval is one of the biggest and easiest skirmish maps in AvP2. In the map, the player plays as a marine that crash landed his dropship into a big swamp. The swamp is pretty big, all green and mostly flat. Due to the terrain being so large and flat, the player can easily spot enemy aliens and shoot them while back-pedaling. In my playthrough of skirmish maps, I typically try to survive as long as I can. As I played Primaeval, I began to realize I was surviving too easily, so I blew myself up to end the game. The map is fun, but it could use more of a challenge to keep it interesting.
