This is an awesome "Metal Slug" clone, shooting game, where you've to infiltrate into the enemy territory and shoot down all the hostile guards that come along your way. Destroy the enemy tanks and choppers without getting killed. Rescue the prisoners along the way, they'll give you new weapon upgrades, health packs or points. You've got limited ammo, so don't let it waste away. If you get killed you'll be able to continue the game with a new life, but if you lose all your lives then sadly, it'll be game over.
