From the developer of Alliance of Valiant Arms (A.V.A), this is Metro Conflict, a modern day-themed online shooter. It was first revealed at G*Star 2010 to much attention due to the graphics and how Red Duck Inc is going to do one better over A.V.A. The standout feature here in my opinion would be the ability to wield 2 different guns at any point of time during gameplay.
However, don’t expect to be able to hold 2 sniper rifles, it seems this is restricted to only sub machine and machine gun types. 2 sniper rifles would be just unrealistic and unsightly. Enjoy the game footage taken at G*Star 2011!
