Metal Storm for the Nintendo Nes

Description

Metal Storm is an action-platform game featuring six stages with two acts each, and a final boss rush stage.

The player takes on the role of the M-308 Gunner, an all-purpose combat robot with a specially equipped gravity control device. By hitting “Up” and “jump” buttons at the same time, the player can flip from the floor to the ceiling and vice versa. Other games feature a “reverse gravity” gameplay, such as Mega Man 5, and Strider, but Metal Storm is one of the few games to be built entirely around this concept.

The player is also equipped with a gun to destroy enemies. The player can pick up various power-ups including a power booster for the gun, a shield, and a fireball ability for when flipping gravity.^[1] When a stage is finished, a password is provided which saves the score, special weapons, and number of lives left.

Plot

In the year 2501, mankind has colonized the Solar System, but all is not well. On a defense outpost on Pluto, a robot-controlled laser gun built to protect Earth from alien invaders has begun to malfunction. It has turned against the human race, and begun destroying the Solar System. Most recently, the people of Earth watched helplessly as Neptune was destroyed. Attempts to activate the station’s self-destruct system have failed. In a last ditch effort, the player must storm the Pluto base with the most sophisticated weaponry available, the M-308 Gunner, and enable the self-destruct device.  After the final boss is destroyed, the leaders of Earth grant the M-308 Gunner immortality, with the duty to protect mankind from future threats.
