Members - Phobos Incident mod for Alien Swarm

Phobos Incident is going to be a full-fledged campaign for Alien Swarm. It can be considered as a re-imagining or an alternate future for the base that was the place of action in the game Doom. Now four marines are sent to investigate a distress signal in a place that could be Phobos moon base 17 years after. Some things have changed, some have remained.
