Honestly I love single player but it should have a co-op element. Imagine you and a friend free roaming new york killing aliens and cell! WOW! Also mabye a survival mode for multiplayer it would kinda work like gear's horde 2.0 but with larger maps and loadouts at your hands! And a map pack would include 3 maps and 2 survival maps.Do you think they should do both or one TELL ME IN THE COMMENTS!
