Now this is a very fun and very challenging game overall,one of the things I thought that only a elite gamer could beat is how many clans of robots spawned and chased you around the map.Ok I thought this was a little unfair at first because of the fact that the large ones had very big health bars and considering the fact that hundreds of them come running I soon found out that I was actually a lot faster than them.But since the robots don't exactly come in what we call "waves" and instead more like a apocalypse,as the number increases and never stops the lag increases a lot,and when I mean a lot I mean a lot!I could barley move to go find a weapon.So yeah that is my only complaint.The other thing is I would recommend decreasing the big robot's health bars just a tiny bit cause I played this game for about 1 hour today and still could not kill one.
