It seems that the wildly successful Horde mode from Gears 2 gave the developers the idea to turn the tables. In Beast mode you play as Locusts. But not just the plain old kind from past MP, no no no. From tiny(but deadly) Tickers to blood thirsty Berserkers, players will be able to play as those and everything in between.
You’re mission, of course, is to eliminate the COGs and unlike Horde you have more than one life to do it. Now there is a ranking system. This means you will have to wait to rank up to play as different Locusts.
I have a feeling this game mode is going to be insanely popular.
