Max Steel game - steel defense

The aliens have reached Max Steel’s secret base. It’s quite difficult for a guy to keep the defense, because the onslaught of the enemy is very serious. Move from cover to cover and shoot at the enemy at the same time. At each level, you need to eliminate a certain number of enemies in order to proceed to the next stage of the operation. Try to do it quickly, not missing the opportunity to earn a bonus for speed.
