Robokill 2

Fight through missions on Levitan and clear out the forces using it as a warship base. In Robokill 2, you play a rebel machine that pushes back against alien creatures and hired robots to defend the planet. Pick up cash and gear after battles. Those finds increase your unit's power and open the way to a stronger combat build.

How to play?

Move into enemy-filled areas and fire on anything blocking your advance. Collect dropped money plus useful items, then use them to upgrade your robot between missions. Keep building your loadout piece by piece. With enough upgrades, your machine turns into a heavy avenger that can wipe out tougher targets.
