I'm running a weekly campaign, and I'm soon to be running a scenario in which the party and their enemies (of which there are three seperate groups) are trapped in a buried temple of a long gone evil race, and they must work together to get out alive and to stop something even worse from happening. The scenario is kinda inspired by Aliens vs Predator. I've got the specifics of the scenario, but what I am needing now are some maps to scavenge, maps of a small-to-medium-sized temple or research complex. They're not expert dungeon crawlers, so nothing overly complex.
Any suggestions? Any major published module will do, as I have access to a lot of things through a store at which a friend works. And no, I'm not making them myself, mainly because I am absolutely awful at map-making.
EDIT: The more I think about it, the more I would like to see examples of dungeons and tombs in other modules in which the floorplans are shifting, where walls and rooms change as the players move through them. Has anyone seen something like this implemented well?
