For your game you could do many different things with that, i think a cool idea would be to make into a survival type game, have enemy's come in from the air and sides attacking you while you run around with powers killing them, since guns are over used you could create abilities like "bro fist" "pug blaster" or have an ability that summons a digital Marzie(probably spelled her name wrong sorry) to help you. thanks for reading if you actually see my reply to this. i hope you take my suggestions …
