For all of you Warhawk owners, there will be more downloadable content coming soon. 1up has spoken with Dylan Jobe, game director for Warhawk and has uncovered some interesting stuff.
First of all, there will be a booster pack in the near future titled Operation Broken Mirror, which will include a new battlefield, an APC, and one new vehicle. He also stated that as long as people keep playing it, Incognito will keep creating content for it. Sounds reasonable. So keep playing it then!
