Place cars along the border line; merging two identical ones will lead to an increase in the level of the car. When installed in a position, the vehicles will fire automatically from the turrets that are installed on the roof. Each newly created car will be more powerful than the previous one, the attacks do not stop, so you need to merge faster. The attacks will intensify, the enemies will increase their strength, so you need to provide stronger defenses to counter them in Merge Cars: Defense.
