Powerslave / Exhumed is a Build Engine 2.5D FPS developed by Lobotomy Software. Saturn and PS1 versions exist but they are almost entirely different game. This page is for the DOS version of the game.
One of the greatest FPS games ever made. Timeless classic.
A build game set in ancient Egypt, what's not to love?
Unused plot and atmotsphere in a FPS of the 90s. result in a nice game. The console version is better, but thanks to the modders this version is now in PC.
