Here are all the game modes in the final game
eath Match (Shoot your enemies in the face)
Elimination (Eliminate Other team)
Plunder (Fight for treasure)
Turf War (Hold as many zones as you can)
King of the Hill (Hold the Hill)
Chain Reaction (Captures the zones in order)
Survival (Survive the waves of Soldier)
Gold Rush (Steal the treasure from the soldiers)
Co-op (Survive with your friends)
Machinima (Machinima mode)
it sounds like king of the hill is a free for all(FFA) game mode. But I'm still bummed that they didn't put a straight out FFA mode.

He said "more maps & more MODES". I'm hoping that will be FFA
