Ever wonder what would happen if the worlds of Metal Gear and Super Mario crossed over? Well that's what you'll find out in Metal Gear Koopa Episode 1: Infiltration.

Mario finds himself forced into an anti-terrorist operation under the command of Colonel Toadsworth. He'll have to use all of his skills (Or pure dumb luck.) to rescue two high profile hostages and stop a nuclear launch from destroying the Mushroom Kingdom. What vile evil could be behind such an affront to a peaceful kingdom? Mario's own younger sibling; Luigi, and a group of specially trained mercenaries. Will Mario be able to successfully infiltrate the enemy stronghold undetected? Watch and find out!
