After being unable to launch the game after buying it on Steam, decided to see if this version would work instead. And yes it did, flawlessly. Rekkr is a First Person Shooting in a Medieval Dark Fantasy world in the same vein as Heretic or Hexen. This is a GZDoom engine based game so it uses a modernized classic Doom engine. Feels smooth, responsive with tons of options available to customize how you please, except for jumping seems to be disabled for some reason. The game itself has it's own unique take on this sub-genre with it's own unique weapons and enemy variety. It is quite brutal and unforgiving so expect a really tough time if you play on the top two difficulty settings. Ammo is very scarce and enemies with often kill you in less than three hits. The levels are large and very well designed to give you a sense of exploration in a semi-nonlinear way. Overall: definitely a recommendation as games in this sub-genre are hard to come by and this is a well done one for sure.
