Who was played Gear's 3 beast mode? What if they did something like that? Basically it is a mode where you first choose a map, it loads and in the first wave, there are maybe 3 or 4 marines, in the character selection, there are 3-6 things to choose, each one costs a different amount of money (which you earn from killing marines and spartans). As it gets harder, marines become odst's then spartan III's then spartan II's and instead of hereoes liek in gears 3, you could have heroes from this. Jorge, Fred, Grace, Holly, Sgt. johnson, Ash and so-on. The boss would be chief.
