I am making a hand to hand melee game and i am struggling to come up with a setting.

The basic story is that you are a bounty hunter with amnesia that goes back to the "hub" and finds the they are under contract to to out 6 high level targets.

The powers come from within the people of this universe and can be harnessed through equipment like gauntlets and shin armour (idk what its called), explain why they don't use weapons

Could you help me come up with a setting for this game, I am currently leaning towards sci fi but I feel like the mysterious sci fi bounty hunter is overdone and won't stand out enough, please help thanks

Edit: slower, more deliberate third person combat
