Solid map. I recognized this right away and the new tweaks are good. The SMEJ monsters and Copper gameplay changes are a nice change of pace from id1. The Doom textures and music are great. What I liked best were the "invisible" Fiends. Just dim enough to catch you off guard if you aren't frosty. I died a few times, mainly to the tight spaces and rocket splash. But that's on me. You'll want to find as many secrets as possible on this one.
