Metal Slug Rampage!

Metal Slug Rampage is an unlicensed flash-based version of SNK's franchise. This time around, the player takes control of Marco who has become bored with saving lives and instead decides to go on a rampage and attack enemy soldiers, crush cars with the Metal Slug and attack innocent civilians such as construction workers. Along the way, Marco (the player) squares off against fellow Metal Slug members who are attempting to stop his rampage.

Gameplay consists of using the "Left" and "Right" arrow keys to move the Metal Slug with the "Ctrl" key for firing the cannons and the "Up" and "Down" arrow keys to move the cannons into their desired direction. The "Shift" key is used for jumping and the "Space" button used for firing the cannon. The goal of the game is to reach the end of the level, destroying enemies and facing off against level bosses in order to advance to the next level.
