Heres me feelings on Warhawk.
GRAPHICS : Very good for a game 5+ years old
GAMEPLAY : No campaign, so have fun w/ online only spawning in & getting endlessly owned by people who play all the time. No tutorial, you learn to survive as a storm of bullets rain on your head. Enemies camp out where you respawn and insta-merc you way too often.
DEPTH : Decent array of weapons, also legit that you can ride vehicles, aircraft and even defend your turf with missile turrets. While the lack of single player is tragic, online play stays interesting.
PLAYABILITY : Pretty fun if you are used to games like this and get into it.
This game stinks. No one even knows about this game and you need to join peoples games, but no one plays this game. It's just a game with war transportation all about playing online with people when know one even plays. There isn't even a career mode.
