He rushed to the marker, and within a certain vicinity his mutation stopped. But through a hallucination, he remember that Altman had told him about the markers ability to inhibit this organism. Now when he was infected, his arm started to shows signs of mutation. He was killed, placed in the morgue, then turned into an infector. And the microbe created by the scientists, was accidentally injected by one of them. The sample Altman retrieved would go on to create the corruption in the site when he forgot about it. It's a marker from an infested platet that got flung into space from the violence of a convergence event, but corruption material was also with it. The black marker is not a special marker. This is what the fish fed on, and like feeders they died and turned. Altman also took a sample of the corruption found floating about the marker. In martyr, not only did they glean the instructions on how to create this gene sequence, which created a microbial life form that acts like the thing (its unlike the thing in a few ways as well). In stosses case those bodies had been killed by necromorphs, they were already infected when he used the shard. In EVERY single instance of a necromorph being created the person/organism has already been infected with this "virus". This virus the scientist created is what's doing it.

The marker is not responsible for turning people. This is absolutely crazy, the amount of times I've shown this and people still resort to the wiki. The reason the shard worked just like the marker is because it's still emitting an energy source.

I love how everyone just points to the wiki.
