-** SPOILER ALERT! *** The alternate ending on the DVD has Salazar's character disappearing off screen after opening fire in the Nike missile silo. He screams, fires again, then the horde of zombies appears. The film continues exactly as it did in the theatrical release, until, as they escape in the SUV, they pass a building in the exterior of the missile base. Salazar emerges, screaming that he wasn't bitten, and muttering that everyone expects the black guy to die. He gets into the SUV, and they drive off. At that point, the screaming zombie pops into frame.
