Master of Weapon[a] is a 1989 vertically scrolling shooter arcade video game developed and published by Taito internationally and by Profit-Vend in the USA.

The survivors of the war gather their strength and resources in an attempt to bring Earth back to the way it was.

However, without warning, a mysterious mutant entity known as "N" takes over the God System; creating three strange guardian statues based on Greek mythological figures, N manipulates the God System's machines and programs in order to attack mankind.

The survivors create an artificial human called Yukiwo – built to harness perfect dexterity and strength – as well as a super-powered jet for him to pilot in order to reclaim Earth from N. The spaceship starts with a basic photon cannon and air-to-ground bombs.

Special weapons can be collected by picking up boxes with specific labels through destroying transport vessels.
