In Assault Heroes, gamers take on the role of the only surviving member of an elite special forces unit searching for a secret underground lab. Gamers may take on the mission alone or fight side-by-side with a friend in the two-player cooperative mode. Assault Heroes puts players into a heavily armed 4X4, maneuverable speed boat or trusty military-issue footwear, blasting their way through enemy-infested territory while being assaulted by waves of formidable enemies with unrelenting attacks.
