SoulGem Survival

Just an apocalyptic world where this parallel world of a very futuristic earth, called Medite, is basically cursed by a pantheon of identical evil gods. So now humans have all got a ridiculously powerful superpower each, that unfortunately cannot be used for the greater good of the world- As now humans must all hunt down and devour the souls trapped in SoulGems (basically floating diamonds beside every human that contains their soul) at least once a week, or they will die :( So you can get any one superpower of your choosing, however the more you use your superpower, the shorter the one week time limit becomes (on the bright side humans no longer need to eat anything else besides souls as a side effect from the curse)
