The PS4 version of Grave Danger is now available with the Switch version coming June 28 and the Xbox One version.... eventually.
Developer Spotted Shark Studio calls the game an "action-packed adventure game." It's about an unlikely group of heroes and lets players switch between Dante the cowboy, Elliot the wizard, and Malice the reaper so that they may use their different abilities to solve puzzles and make their way out of trouble. The game can be played single-player and co-op.
Grave Danger is rated "E10+" by the ESRB.
