Isolated Warrior, known in Japan as Max Warrior: Wakusei Kaigenrei (マックスウォーリアー 惑星戒厳令, Makkusu Uōriā: Wakusei Kaigenrei (lit. "Max Warrior: Martial Law Planet")), is a 1991 video game developed by KID and published in Japan by Vap and in North America and Europe also by Vap with NTVIC as their co-publisher for the NES. It falls in the shooter genre, although its gameplay also includes elements reminiscent of platforming, while it features isometric projection, similar to Sega's Zaxxon.
The game is shown entirely from an overhead perspective, as in traditional top-down shooters. The player must collect weapon upgrades and operate various machines to combat the alien enemies.
Various obstacles, such as pitfalls and land mines, must be avoided. There is a boss battle at the end of each level, and sometimes mid-level as well. The player's progress in the game could be saved using a password system. Between levels, images and text were sometimes displayed which showed Maverick's thoughts or reminiscence about his life.
The game's plot takes place on a planet outside of Earth's galaxy called "Pan", which is suddenly attacked by a mysterious alien force.
The aliens have the unique power to consume any living thing, as well as machines and buildings. Pan soon becomes overtaken by the alien force and the army of Pan begins losing all of its military power. The soldiers and people of Pan are told to evacuate the planet, however, a captain of the army, Max Maverick, refuses to leave. He instead suits for battle and faces the aliens alone, using a motorcycle and hovercraft as his means of transportation. Max must stop the alien menace or face the destruction of his world.
