The combat systems in Mortal Sin are so visceral that long-term players report near-universal satisfaction after crossing the 25-hour mark. While the initial experience can be jarring for newcomers, 344 positive mentions out of 400 total post-release reviews confirm its status as a top-tier action RPG.
What it's about: Mortal Sin est un roguelike chaotique et sanguinolent où le talent est le pouvoir— et l'excès de confiance signifie : la mort. Frayez-vous un chemin dans un cauchemar généré de façon procédurale à coup de combos brutaux et spectaculaires.

« The first run was amazing, but after a single run you learn that it's really, really repetitive. Just same rooms over and over, spinning to win. It's got some good bones but I got bored pretty quickly. »👎 anonymous review · 5 h played21« Overall, the game has some things going for it, but the DDR/Guitar Hero combo system just takes all the fun out of it and makes it utterly annoying to play. »👎 anonymous review · 12 h played« Gets old very quickly, aside from that the graphics and gameplay are good for the first few runs »👎 anonymous review · 5 h played« It was fun for a couple of hours but fell flat. I don't feel like the roguelike features are integrated enough. Most of the upgrades you get don't feel impactful. I don't think theres enough content here to warrant it's price either. »👎 anonymous review · 3 h played« No depth. The combat is just you overwhelming the enemies, thats just childsplay. Poor balance. No fun. »👎 anonymous review · 24 h played« I was playing this game while waiting for silksong to stop crashing steam. But then I enjoyed this game more, so yeah its fun »👍 anonymous review · 10 h played21
