FireLine: Merge Defense (FireLine: Merge Defense)
In the game FireLine: Merge Defense you have to lead the defense and this business will require you to think strategically. You will be given a cannon that will fire by itself and without your efforts, but you must improve the weapon endlessly. You will be able to make your gun fire faster, more projectiles, and you will also increase the number of guns. To do this, you need to merge guns with the same parameters on a special field in the game FireLine: Merge Defense.
