METAL SLUG ANTHOLOGY

The end boss of this level is a hover craft type plane. Sword enemies and cannon enemies will climb out the side and jump down or fire at you from the plane's side decks. The plane will also occasionally blast fire from it's hover engines making it so you will have to stay directly under the plane and move with it to avoid being hit by the fire (usually while also avoiding enemy fire from above). To beat the boss, just keep firing away and throwing grenades at it as much as possible as you avoid the attacks. Your camel cannon is very helpful as well if you still have it to help drain down it's energy faster.
