i really hope there is some type of multiplayer in the next game because lets be honest, this game gets old after a while. so okay there cannot be mw3 or fps type of multiplayer here. thats not arkham. here are my proposed ideas. leave your own in the comments.
THUGS VS BATS- now the name sounds goofy, but think about it. 10 players online are thugs- then you have 5 players as: one is batman, one is robin, nightwing, catwoman, and maybe batgirl(before the incident). thugs have guns, like a third person shooter, bats use their gadgets and stealth. thugs try to kill bats. bats get points for eliminating thugs. sort of team deathmatch.
CO-OP CHALLENGES- now in arkham 3 i hope challenges improve. for instance instead of challenges taking place in one little room, they are now taking place in multiple buildings and rooms. over rooftops, in a large building with way more enemies, and maybe even an objective . now you and up to 3 friends are fighting in combat, and taking out guys in predator and see who gets the most points taking out the most guys, the most creatively.
have any more ideas. dont like mine. sound off below people.
