Looks very cool.

It's like TF2 meets Mirrors Edge and Killzone. definitely has my interest though. the trailer has me impressed.

i made a few GIF. images from the trailer to celebrate this i guess.
Crushing a giant (Greek?) dude with a tank of some sort (Had to speed up and use a smaller size)
A Rastafarian going all matrix and blasting a Security dude with a Grenade launcher
A nice summer view of the ARK
