A shooter thats supposed to be a mmofps with most of your time geared towards PVE so yeah there is. Borderlands is a shooter just like this one its just not online. And there's a very noticeable difference from being lvl1 to lvl20 in terms of power, damage dealt, and how much damage u can receive. Its just this game doesn't have a leveling system in the tradition sense. So its more like an online gears of war. Just giving some constructive criticism.
