That is an interesting screen. Sure it's a promo shot, but i believe it's part of an MP map. They did this with Crysis 2 as well. They had promo shots of nanosuit's in action in what turned out to be parts of MP maps, and this is the only glimpse at a map other than Museum, so this is an interesting lil promo shot.
The map looks gorgeous, glorious forest environment reminiscent of Crysis 1. It's great to see a VTOL in the back, hoping it's not just a prop like the choppers in Extraction
My first thought was that it's just hunter mode in a different map, but you did a great spot there noticing the Scar in the hands of the nano guy. Perhaps we'll see more of CELL Vs. Nanosuit modes in MP. A good change from the regular deathmatch if you ask me.
