Captain America and the Avengers is a one- to four-player side-scrolling beat 'em up where four Marvel Comics licensed heroes - Captain America , Iron Man, Hawkeye, and Vision - battle against the evil Red Skull. The Red Skull has assembled a team of super-villains to conquer the world.
The game consists of five stages, with primarily side-scrolling brawler gameplay, but some levels also feature side-scrolling shooting stages, including stages set in the air, under the sea, and in space. The heroes face off against various bosses, including Living Laser and Klaw, Whirlwind, Grim Reaper, Wizard, Mandarin, Juggernaut, Ultron, Controller, Crossbones, and the Red Skull. Additional allies include Quicksilver, who drops energy replenishments, and the Wasp, who adds protection and firepower in shooting areas.
