Eco Fighters (Ultimate Ecology in Japan) is an arcade game released by Capcom on the CPS-2 arcade system board on December 1993. The game is a horizontal shooter, where the player controls a ship with a rotating gun. As suggested by both its titles, the game has an "eco-friendly" theme. It was also developed by the same team from two Mega Man series arcade titles, The Power Battle and The Power Fighters.
Capcom re-released Eco Fighters for the PlayStation 2 and Xbox in 2006 as part of the Capcom Classics Collection Vol. 2 and Capcom Classics Collection: Reloaded for the PSP. The game is also playable on the GameTap online service.
