The idea came up in a discussion with friends recently. We all felt like playing coop but had 5 people in party. Wouldn't work in Adventure without some major tweaking but why not Arena? Ramping up the difficulty essentially just adds tougher enemies, would it be technically feasible to modify a multiplier to provide for the extra players/protagonists?
Would anyone play this other than me and my peeps?
Oooh. 4 player! They'd finally use all the real estate in split screen! Good point.
Some maps would be tight to be sure..for me, that just means more cooperation. My style is to stand off the action in support and let my more "agressive" friends mix it up in close but I think I'm the exception so yeah, that point is well taken also.
