Play Alliance of Valiant Arms or Combat Arms (or practically any F2P modern military shooter) then this. It's practically the same thing. What sets it apart?
I played both of them, and excuse me but a metric ton of things?
Graphics, devs, weapons, maps, systems, business model, unlocking model, sounds, shooting handling, attachments, sliding, coop, pretty much everything that sets every other game on the market loving apart?
By your logic there's no reason to play any FPS game anymore because it's all the same crap. Nor any medieval strategy or management games. Or physically any games of the same genre & sub-genre.
