Scientists experiment with ancient teleportation system between the Earth and Mars' moon, Phobos. Meanwhile space marines are sent to help out with security. What could go wrong?

While not exactly Isaac Asimov, the plot set up vaguely holds water, the production design belies the low budget and the marines have enough personality sketched in to be interesting. So far so good.

The failure is in the action department, Doom should be packed with beasties but for 7/8 of the movie all we get are a few lacklustre zombies. Disappointing.
