Disco Samurai is a game that’s so difficult I’d have given up playing sooner if it didn’t contain so many of my absolute favourite action game things. Tense, decisive duels. Violence that’s both brutal and a little silly. Scalpel-sharp parry n' strike back-and-forths. Short stages that dole out chunky progression hits of dopamine, as quickly as they wrest those hits away from you with another humbling beatdown. Perhaps most importantly, it aims to do one thing - rhythm combat - and does it brilliantly. It's got teeth, but it's also got groove.
