This is a four-player co-op mode, that can either be played alone, split-screen or online, similar to Horde.
It sees players securing a series of positions before holding them against waves of enemies.
EGM’s TAKE: What it doesn’t make clear is whether split-screen will be limited to two player co-op or four? If it’s four then this game just went up in our expectations, as we all miss the days of couch co-op with all our friends. Apart from that it appears to simply be the usual beat waves of enemies for points affair.
