Onion Force

All the kings are dead… Except one.

Onion Force is a hybrid Tower Defense/Action Adventure game with 30 levels of butt-puckering mayhem! Use cunning and strategy to strengthen your team chosen from a diverse cast of characters, and hang on to your seat as you try to save the last king from his doom!

Make intelligent choices, collect gold, onions, and equipment. Build towers that will be most effective for the threat at hand. Decimate evil through an array of terrain, weather conditions, destructible environments and utter chaos to find the source of this nonsense.
