After creating "one of the best tower defense games" (1, 2, 3, 4, 5, 6, 7) with Core Defense, solo indie developer Mario "ehmprah" Kaiser is setting out to create yet another minimalist, unexpected fusion of game genres with Blacken Slash.


A tactical RPG fusing the best of roguelikes, turn-based tactics and hack and slash games – made by a solo developer with a penchant for minimalist designs.
  • Fight through bite-sized tactical puzzles
  • Create powerful builds from a plethora of items which grant you skills and can change gameplay mechanics
  • Carry on your favorite items between runs in normal mode
  • Start from scratch each week and compete with other players in the online ladder mode
  • Try various playstyles and hunt for challenging achievements
  • Enjoy a lovingly crafted story of ridiculous computer nostalgia and a blast of a retro soundtrack
