The demo was simply AMAZING! If you haven't tried it, DO IT! Arkham style combat synced to the beat of the game's music & it even supports custom tracks! SCORE!! Kinda like Hi-Fi Rush but all the pure music adrenaline pumped straight into your veins. I can see a huge potential for mods to really add to the replay ability aspect later down the line. I'd be ecstatic if this came to GOG.
