The updated is called Ghosts of Meridian and it adds two new maps, Tyrant for Arena and Skirmish at Darkstar for Warzone. 343 is calling Darkstar “the most condensed” of all the Warzone maps, with greater focus on infantry gameplay. Darkstar will also feature new bosses.
And some new toys. Still waiting to hear about community maps in BTB (I think they added a few already)
I just picked up a digital copy last night for $30 on the xbox store. I couldn’t pass it up and I need a new shooter. Expect to see me on there shortly.
