Aliens vs Predator 2 singleplayer custom map titled "Ruinous".
Map author: Phil 'Windebieste' Wlodarczyk
Ruinous is a marine based skirmish map, in which the player is placed in a dm_compound looking map that is filled with ancient pillars. Ruinous is one of the best skirmish maps for AvP2 in that it has a good balance between not being too difficult, yet still providing a challenge. As long as the player keeps moving, they will probably stay alive. However, if the player is cornered, grabbed by a facehugger or falls off a cliff, it can spell certain doom for them. In the video above, I replayed the map a second time just to grab the exosuit. It's not too hard to get once you know where the torch is. Overall, Ruinous is a good map.
