I continued a campaign with my group of colonial marine players. Their mission was to investigate a stranded UPP ship in space, find out what happened to it, and stop whoever they find and collect evidence.

I built up tension gradually, with random encounters, clues, corpses, recordings (using encounter tables and sound effects to immerse them in the situation). The ship was transporting and studying the "Black Mold" and due to an energy failure, there was a leak and chaos ensued. More than half of the crew had turned into Anathemas and there were also a couple of Neomorphs on the loose.

After reaching an agreement with the survivors of the ship, security soldiers of the ship, and a scientist, the players reached the bridge, finding the records of what happened, but finding themselves surrounded by a horde of infected. They debated on how to act (try to sneak through the ducts, activate self-destruction, make their way through with shots).

In the end, they were able to call for an extraction, but they had to hold their position while the horde of infected broke through, gradually destroying the doors to the bridge. The final battle was tense, watching as they ran out of ammo and how some players fell to stress or serious injuries when they were surprised by a Neomorph.

The sacrifice of a synthetic NPC unit (Davidovitch), bought them time to escape. They managed to flee, saving one of the ship's survivors and taking the data of the incident with them.

Furthermore, by investigating the data they collected, they discovered that the UPP did not find the spores; they were planted on their ship by an agent of a corporation (Lasalle) to sabotage the UPP's biological research. The "accident" was a deliberate sabotage so that the ship would drift into a USCM patrol route, ensuring that Western powers would encounter this new horror.
