Have you missed boss fights? Old fashioned games where you try to kill a boss and die again and again are back. Grab a cannon and try to kill various bosses dodging their attacks.
The ultimate boss wants nothing, but kill you. There are no targets around and he sees only you in front of him, so there is no other choice, but kill the boss. Who will become a winner out of this situation? You are agile and fast, but your enemy is big, slow and powerful. Use your advantages to strike him when he is weak and win the battle!
