You asked - we added. Come to the garage.

A new module has appeared in the garage - Sapper! Place mines right on the battlefield. If the enemy runs over them, they'll take serious damage. Upgrade the module so that the mines hit harder and the reload time is faster. Mines are a consumable. The starting supply is limited, and you can buy more in the shop. Use them wisely! And to have enough coins for the first set of mines - here’s a promo code: MINER001
