Romero knocked this one out of the park for the most part. This is probably the most interesting use of Doom 1 I've seen, with really well designed maps that have great use of encounter design, ammo conservation, and enemy prioritization. Love the use of slow walls to keep you within an encounter and deal with it especially, forcing you to employ the deeper mechanics of doom movement and strafing.

It's not exactly perfect, the Doom 1 enemy roster sets it back a little and there's a couple maps with some... questionable decisions on placement especially when it comes to lava-immune suits. But damn was it a great time, had just as much fun as I usually do with Doom 1 with it if not a little more so. Also the music owns. (8/10)
