I love the perspective here, a couple of scavengers on a Battle Brothers ship. The present tense is effective in evoking a sense of immediacy, and you do a good job with adding a bit of humor and light-heartedness to an otherwise tense situation.
It's tricky to do present-tense well, though. There are several places where you slipped into past tense. For example, "Maric was not looking at him" should be "Maric is not looking at him". Swapping tenses tends to break the illusion, and dropped me out of the story several times.
Great ending, though! It really nailed the atmosphere of horror you built up through the rest of the story.
