Description from the Heavy weapon wiki:
"TS-31 Kriznek Carpet Bomber take a role as a strategic bomber that will drop 4 bombs in a row.
Since the weapon is dumb bombs, they should be easy to destroy. The bombs only drop in a small areas, make it easy to maneuver."

I cannot figure out how to make the cockpit from the tiny sprite of the game. The aircraft ended up looking like Thomas the strategic bomber's cyclops cousins. Armament wise, the plane carries 12 bombs. The engines are quite powerful, as such, there is no need to go full throttle. 50% should be enough power.
Caution: Be careful when dropping bombs. You should keep the plane stable as the bombs may collide with the plane mid-air, blowing you up in the process.
