Four months ago, Black Knight Sword hit both XBLA and PSN and got fairly high marks for being a great action-platformer with a really sick sense of humor. Starting tomorrow, April 16, the game will be half-off on XBLA, and only cost 400 MS points, or $5, instead of 800. BKS has some of the most distinct visual styles out there, and while its core gameplay is a bit rough around the edges, the game is so creepy and unsettling that it’s nearly impossible to stop playing once you start. Anyone who loved 16-bit platformers that tested not only your platforming skills, but also required you to do some puzzle-solving ,will really enjoy it. $5 is an absolute steal given how memorable the game is.
