Blood Knights has been released on the Xbox Live marketplace. It’s a violent action RPG with some surprisingly rich graphics for a download-only title. The gameplay looks fast-paced, with a blend of God of War-style action, platforming, and co-op gameplay so you and a friend can rid the world of evil online. It will set you back $15 on XBLA, and will cost the same on Steam on November 14, and on PSN on November 20. If you’re in the mood for some bloody action-heavy gaming, give the trial version a shot for free. It will take up about 1 GB of space on your hard drive, so be sure to clear some room if need be.
