A lil alien magic is okay, the creature itself is infused with traits that don't seem possible. I just wish the "xenovirus" was a little more consistant I guess.
From all life creation, Trilobyte std's, Fifield monstering, deacon birthing, xeno-jungle ecosystem creating, Mt. Deacon making, elden thing-ing, Cancer hulking, alien / human body melding, brain deteriorating, all animal life killing, to neomorph creating. There just doesnt seem to be much of a rhyme or reason to it all.
