Metal Warriors is a side-scrolling action-platform run and gun video game developed by LucasArts and published by Konami exclusively for the Super Nintendo Entertainment System in North America in April 1995.
Development on the project was immediately approved by Kelly Flock after release of Zombies Ate My Neighbors in 1993 to positive reviews and took influence from various mecha anime series and video games, most notably Cybernator.
Metal Warriors garnered positive reception upon its release from critics, who praised various aspects of the title such as its presentation, visuals, gameplay and multiplayer but some of the reviewers felt divided in regards to the difficulty, sound design and lack of passwords for game saves, while many also drew comparison with Cybernator due to its similar mechanics.
[3] While ejected from the suit, players take control of Stone, who is armed with a pistol that is useless against all mechanical enemies with the exception of soldiers and scientists lacking armor, in addition to a jetpack that enables him to fly in a similar manner to the Nitro but slower.

[13] LucasArts' Kelly Flock immediately greenlighted work on the project after development process of Zombies Ate My Neighbors went smoothly without major issues and the positive critical reception it garnered, with Ebert himself claiming to be surprised at the company's decision.
[11][13] Metal Warriors shares the same game engine written by former Sega of America technical director Toshiyasu Morita as with Zombies Ate My Neighbors, albeit modified and improved upon its previous iteration, which allowed its creation process to go fast and smoothly.
[13] Ebert has explained in recent years that the team had originally desired to implement a split-screen two-player co-op mode in Zombies Ate My Neighbors but it was not possible due to the engine not being fast enough at the time, however they were able to do so on the project.
[7][16] Sharpe has since stated that a version for the Sega Genesis would not have been possible without his involvement due to several programming tricks used in order to run the game on the Super NES, before the idea was ultimately scrapped after Nintendo picked up the project for release.
[13] Shortly after Metal Warriors was published in stores, both Sharpe and Ebert would depart from LucasArts because of internal issues that occurred within the company with Flock's departure to form their own studio, Big Ape Productions.
