Run up the stairs in Gun Masters and shoot the gunman waiting for you on each floor. Watch your gun’s sightline and shoot when your gun is tilted at the right angle. Try to hit each gunman with your first shot, because you won’t get a second chance: you might miss your shot, but your gun master enemies certainly won’t miss you! Collect coins to unlock rare guns and other special weapons. There will be a boss waiting for you at the top of each staircase!
