Welcome back to the Synergenic Technologies Testing Chambers in this spiritual successor to the "Prototype Mk2" and Prototype Mk3" Campaigns. Fight your way through a strange, minimalist world to escape.

This campaign relies on heavily tiled, small size textures to reduce rendering impact and, hopefully, support more zombies. Because, once again, this campaign utilizes scripted zombie spawning. 

I left the rescue closets in the map for versus mode, I hope that doesn't cause problems, but we'll see. 

This campaign is deliberately designed to be hard, just like my previous campaigns. It should be beatable by most people on the Easy difficulty, but I expect it to be challenging to even experienced players on Normal and Advanced. I hope it's downright hard on Expert. It may not even be beatable on Expert-Realism. 

I had a lot of fun with the art-direction on this campaign, and I think it's another pretty unique-looking campaign. I hope you enjoy this new nightmare of a campaign as much as I enjoyed making it.

Happy zombie fighting!
