Fantastic action RPG from the makers of Bastion, currently sitting with an 83 score on Metacritic.. This will be on weekend sale from now until Monday 4th August.
It has only been out for two months but this is the lowest price so far. The previous low was 25% off in the Steam summer sale.
It will certainly hit lower sale prices as the months pass but there's no doubt that it's worth it at this price if you're looking for a top (and relatively new) action RPG.
