Fight your way through a locked down UAC base, and close the portals to hell in this unofficial expansion sequel for Doom 2! On December 10th, I'm releasing a PWAD for Doom 2 to celebrate 30 years of Doom! Using only the original Doom 2 texture set and mapping functions, I have crafted four maps with a high level of detail and only one difficulty: hard. These are the first maps I've ever completed, I hope you enjoy them.
