What kind of game series is Gundam Versus ?

I heard a while back that it was like a PvE focused game were a group of players defeat a very tough boss type robot. But all the videos i've seen seems to indicate this is just a PvP game. I know it says versus on the title and it's a given that it might just be a gundam pvp fighting game but i was given false information / or what not. Or am i confusing games?
