“Single player co-op?” you ask. The unique game mechanic in Reset is the ability to travel back in time to solve puzzles co-operatively, with yourself. Confusing? Light will be shed.
So that sounds like that Super Time Force game that's being worked on right now. Except that one is (another) retro 8/16-bit inspired 2D side scrolling platformer shoot-em up kind of game. And you can have literally 30 of your own doods running around the level with you. This game looks way better and I'd like to see how they incorporate that game mechanic into a 1st person viewpoint.
Also, when I saw the thread title I was like, wow they are making a Hard Reset prequel already?!?
