In the first-person action game American Block Sniper Online, set in the Minecraft universe, your objective is to clear each level of all adversaries before the timer runs out. You begin each level with only a rifle, but youll discover and equip a wide variety of weaponry as you go. It takes anything from two to five minutes to complete a level, give or take depending on your score. At this point, you should aim to vanquish every enemy that shows up on the map.
