Serious Sam Fusion: Mitosis - Serious 100%
A very good combat puzzle map, it requires the mastery of movement and good strategizing. This is probably the first time I see custom enemies being benificial to the map rather than detrimental, truly groundbreaking stuff. I overlooked this map initially, thinking it was just another workshop atrocity, but thanks to Steak Jacobs I've learned that it's actually a gem floating in a sea of excrements.
And yeah, I had to flex that I can beat this map.
