This game is so hard !!! The enemies will hit you almost everytime and most of the time you will end up with out ammo when surrounded by a large number of enemies . BUT THIS IS STILL FUN !!!
I never spent time customising inventory till level 9 then I realised I can upgrade my armour but I have to drop existing one first , it always said armour full when I try to buy new one. It is one shot adeventure and story is short which makes sense it was launched as dlc at first.
