"Sometimes a game has a mechanic so brilliant and works so naturally that I can’t help but wonder where it’s been all my life. Super Time Force revolves around such a mechanic: Single player Co-Op.
Every time you die, you start over. The hook is that your last attempts do as well, fighting alongside you before they repeat their grisly demise. If you die enough, you can amass an army of failures and maybe, just maybe, have a completely successful run."
