Play Gun Masters and climb the staircases to reach the final boss waiting at the top. In each level, you will encounter one of the boss’ henchmen on each floor of the building. Use the laser sightline on your rifle to aim, and fire a single bullet when your gun is tilted at the right angle. It’s important to hit your enemy in one try, because the enemy gunmen won’t miss if you give them the chance to fire back! The boss is a little tougher and will take multiple shots to kill. Make sure you don’t miss. Save up points to unlock cool new weapons.
