About game
An enemy convoy is advancing on your desert base. Command a repair robot, move between six construction platforms, and deploy machine-gun, cannon, and rocket towers. Enemy tanks can fire at your defenses and the robot, so damaged towers must be serviced using metal. After every wave, the engineering department offers three random projects, but only one can be implemented. Combine tower types and upgrades, protect the gate, and survive all 20 waves.
How to play
Move the repair robot with W, A, S, and D. Drive close to an empty circular platform and click it with the left mouse button to select a tower. Click a constructed tower while the robot is nearby to upgrade, dismantle, or repair it using metal. Stop enemies from reaching the gate. Between waves, choose one of three engineering upgrades. Use Pause to stop the game and Sound to mute effects.
