I hated this game at first I was dying a lot until I learned this simple trick.

Enemies beneath me were killing me and I couldn't figure out how to shoot them since there are no instructions for the game. I thought this game was chocked full of cheap deaths for two hours then I finally figured something out. YOU HAVE TO JUMP IN THE AIR TO SHOOT DOWN. This is the first Metal Slug game I've ever played so I had no clue how you do it. That's how, so if you never played and can't figure out how to shoot those bastards underneath you now you know. A simple instruction tutorial would be nice.
