METAL MECH NINTENDO NES

You control the pilot of a MetalMech vehicle (which looks like the ED-209 from Robocop licenses) who can move across the screen left or right, with or without the mech, and fire in any direction except down. The Mech is better armored, but also a bigger target and far too big to climb ladders, so you'll find yourself both outdoors and indoors. Your objective is to go through each level filled with randomly generated enemies and reach the next one. Power-ups are hidden in various containers and in various locations.
