''Metal Black'' is an [[ArcadeGame arcade]] ShootEmUp released by Creator/{{Taito}} in 1991. It was orginially supposed to be a sequel to ''VideoGame/{{Darius}} II'', but the developers decided to make it a separate game, though it is referred to as ''Project Gun Frontier 2''.

Your ship is able to collect many small power-ups to build their weapon's power. Players could then unleash a large beam attack or a screen-filling energy burst that would drain their power level back to zero.

'''Story:'''

The year is 2042: Earth gets invaded by aliens intending to [[PlanetLooters plunder]] Earth for inorganic materials. Both the aliens and the star they came from became known as "[[NamesToRunAwayFromReallyFast Nemesis]]". Earth's troops put up a fight, but were outmatched by the alien's powerful beam weapons. However, Earth's scientists managed to obtain the aliens' weaponry for Project Metal Black, which focused on developing at least 20000 human space craft with the same beam weaponry. The space craft was known as the CF-345 Black Fly.

Ten years after the invasion, Earth unconditionally surrendered to the aliens and promised to keep all of Earth's remaining forces from attacking. This applied to Project Metal Black as well and sealed the Black Fly space craft from the people. The aliens ended up devastating Earth anyway via draining its natural resources, and the dying planet's capacity to sustain its population was rapidly diminishing... it was only a matter of time until someone discovered legacies of Project Metal Black and struck back.

!! '''This game has examples of:'''

* AfterTheEnd: The aliens have managed to conquer Earth and diminished Earth's resources. Stage 1 (a wrecked city) shows the extent of the damage done.
* AlienInvasion: And the aliens actually win and succeed. The story takes place after they manage to ravage most of Earth.
* AmazingTechnicolorBattlefield: The [[http://www.youtube.com/watch?v=a9my8sMlw-Q final boss]] Omega Zone definitely counts.
* AttackItsWeakPoint: Most of the bosses have a single weak spot which you have to hit in order to damage them.
* BeamOWar: You SmartBomb fires out a giant beam laser when the button is held down. It is able to counter enemy shots, as well as the WaveMotionGun that the bosses use.
* BigCreepyCrawlies: Daio & Gishiin, a mechanical dung beetle rolling a ball of scrap metal.
* BittersweetEnding: The bad ending. TheHeroDies, but inspires the rest of the military to resume fighting. 20000 Black Fly ships set out for battle.
* ChargedAttack: Collect-type. You collect particles of "Newalone" energy to power up your beam cannons (which act as a SmartBomb or a WaveMotionGun).
* CollisionDamage: Against almost all enemies. However, averted by the FinalBoss (only his core can kill you on contact, his body and tail are harmless).
* DarkerAndEdgier: To ''VideoGame/{{Darius}}''. The game was originally meant to be a sequel to Darius II, where the Belser Army had managed to destroy planet Darius.
* DeadlyWalls
* FlyingSeafoodSpecial: Many of the bosses and enemies are based off aquatic animals. No surprise, considering that the game was originally meant to be a sequel to ''VideoGame/{{Darius}}''
* GainaxEnding: See MindScrew below.
* GiantEnemyCrab: The MiniBoss of stage 1 is a giant hermit crab with an ''aircraft carrier'' as its shell.
* GrandTheftPrototype: Decades after aliens destroyed Earth and the world's governments unconditionally surrendered, you steal an experimental space fighter and blast your way through re-animated carcasses of Earth's military forces that didn't survive the alien invasion while attempting to escape into space to fight the enemy hordes. The game has multiple endings depending on if you win or game over in a certain stage, and one ending involves the governments being motivated by your death into bringing another 20,000 experimental fighters into action.
* MindScrew: The good ending. [[http://www.youtube.com/watch?v=a9my8sMlw-Q If you can make any sense out of this, you're good]]. (more pictures [[http://www.vgmuseum.com/end/arcade/d/metb.htm here]])
* PowerUp: Only one kind, which look like three coloured particles stuck together. These things power up your regular weapon as well as charging up your SmartBomb.
* SegmentedSerpent: Feeder, a giant mechanical [[Rat-tail fish]]. Attack its head in order to damage it.
* SmartBomb: Tapping and releasing your secondary attack button will allow you to shock the whole screen in energy.
* SoundtrackDissonance: "Born To Be Free", Stage 1 music. An upbeat, hopeful tune played over the landscape of an Earth utterly devastated by aliens draining the planet's resources to near-exhaustion and infested with not only re-animated remains of Earth's military forces that fell during the invasion but also organisms of the said alien occupiers.
* ThatsNoMoon: You see a moon in stage 2, shortly after leaving Earth. Turns out that you see the ''real'' moon after that, and the first "moon" is the egg of Feeder, the second boss.
* WaveMotionGun: Your Newalone energy cannon, reverse-engineered from the aliens' weaponry. It is able to destroy enemy shots too.
