Machoman), is a side-scrolling platform action game for the Nintendo Entertainment System developed by Aicom.

In the game, players take the role of Amagon, a Marine who is trapped on an island after his plane crashed.

[1] Inconveniently, his rescue ship is on the other side of the island, which Amagon must now cross on foot.

He also has the ability (upon collecting and then activating the Mega-Key) to transform into a larger, stronger version of himself called "Megagon".

Megagon cannot use the machine gun, but instead has a punch which does eight times the damage and never runs out of ammo.
