For the more hardcore geeks amongst us...
1 of my fave geeky maps is DM-LV-426-Infested which is based on the 2nd film from the Alien series: Aliens.
It's got the Space Marines vehicles outside, the inside structure of the colony, and a xenomorph nest built under it...

...with pathing for xenomorphs to spawn in down there and make their way up into the colony to patrol for players they can attack.
From any gametype: what is your favorite map that's based off a movie, television series, comicbook, and/or novel?
