This is an old-ish game, probably from 2010-2014, but the game consisted of you in a flying wooden war machine of sorts, kind of like a barrel with a helicopter blade, and your weapons were things like hammers, swords or flails. There was a story mode and an arena mode, and the story allowed you to take 2 paths, one for good and one for evil. There were many tanks in the game to choose from with multiple different shapes, along with multiple weapons. If there is any more information needed to find the game, I'd be happy to provide.
Oh, another thing, the game started with an a, and it sounded similar to armageddon when said out loud...
