Prototype is a combat simulation test for new recruits into the marines. It quickly determines if the applicant has the necessary degree of badass to get a high score in the military. The simulation accomplishes this by creating an environment of extreme hostility and danger in which the player must survive against monsters, zombies, army tanks, helicopters, Bible Thumpers, hippies, and cars. The player is well equipped to handle this type of hostility by having the combined strengths of six different super heroes.
