It's Doom's insanely fun and revolutionary gameplay, this time with some new enemies and the Super Shotgun. Sadly they have to contest with level design that feels too big for its own good at points, and ends up feeling like the worst sections of Doom 1. Still a solid title that I don't regret my time with, but the level design unfortunately holds it back from me being able to say I truly love it and wanna go back to it like the first three quarters of the original.
