Attack of the Moon Zombies (2011)

Twenty years have passed since Dr. Vincent Edwards took on a certain radiation-mutated bat creature and he is ready to retire. While training his replacement on the Jackson Lunar Base, the two stumble upon a seemingly impossible discovery: alien plant life on the surface of the moon! Unfortunately, exposure to the spores of this otherworldly flora cause instant death. Too bad those killed by them don't stay dead and instead, want nothing more than to replicate!
