5. High Energy Beacon. It can destroy a Z.O.M.G.'s outer shell within seconds!

4. Banana Investments Advisory. Banana Reasearch Facility is better if there are 6 or less, but any more than 6 really helps, especially in Freeplay mode.

3. 2/2 Engineer. INSANELY OP. (I have iOS, not deluxe)

2. Bionic Boomer with Tier 4 building. (On PC, it's the Tier 3 building and Double Ranga) Very powerful.

1. ROBO MONKEY. It only takes 2 to destroy a single Z.O.M.G. AND all of its children. (On long tracks, at least)
