New Game mode needed with depth
Need a new game mode
Look at some of the greatest multiplayer games in the past 5 years.
Gears of war 3 horde mode , fight with a group of 6 and process through the horde
Mass effect 3 a 4 player co op a wave of ten with different objectives
Battlefront 2015 you already did something like this with wave modes 1 player and 2 player options.
Now you have an opportunity revisit this and make it better, a 4 or 5 player co-op against a faction for how many waves you may want. You can still keep the point system in play, (does a player risk all points to become a hero or does he wait until a later wave)
i bring this up is because you need another mode that is different, for the players and at the same time has depth and is not gimmicky like heros vs villains. It also needs to feel as dynamic as galactic assault. Also a refreshing break from player vs player.
