It's been available on Microsoft's 360th console for a while now, but rhythm-RPG mashup Sequence is now available on Steam. I'm tempted to call it Puzzle Quest but with rhythm game mechanics in place of match-3 mechanics and nothing I've seen suggests I'd be incorrect to do so. There's a narrative, character customisation, magic and, underpinning it all, the hammering of cursor keys in time to music, which is how all fights would be resolved if I was the God of War. There's a trailer for the Steam release below, which contains timely and pithy comments about Metacritic. I hope to take a proper look myself when I clamber from beneath the current pile of games entombing me.
Sequence costs a pittance of £3.99, currently reduced by 10% in this, its launch week.
