METAL SLUG ANTHOLOGY

This boss is a cannon type tank that is built into a hut like structure. It has two modes of attacking you. The first one is that it will fire 3 projectiles at you and then repeat the same attack after those have fallen. These are slower moving and easily avoided just by moving back and forth in between them, just make sure to keep firing on the boss in between avoiding the attacks. After it takes enough damage it will switch it's attack to a high cannon beam followed by a low cannon energy ball attack. All you have to do is duck when it is firing the high beam and jump over the energy ball. Just rinse and repeat while attacking until it falls.
