Please note that Microsoft has released a brand new trailer for Evolves devoted entirely to new mode " Evacuation ", in which we will have to defend or attack (depending on the chosen role) a colony and that it will be playable in the Xbox-exclusive One in the open beta of Turtle Rock waiting in January. There are few details so far spread on new mode, but the video shows that can be multiple of 4 hunter and the only monster seen so far. You can find the video in this page ; good vision!
