Sewer Levels are the evil twin of Train Levels, please stop making them.

Solid Boomer Shooter. One i think mostly improves upon the games it's inspired by. I have always thought the Build-engine games looked like ass, but it does it's damnedest to make it look nice. And this also feels much more satisfying to play. The shotgun is fantastic. It has a nice rhythm.

The trade-off i guess is it personality, it feels somewhat more generic than Blood or Duke ever did. It still also keeps some of the flaws those games had, like overly big levels, the annoying tiny enemy type and bullet-sponge boss fights. None of it a deal breaker and i did overall like it.
