I love your story BigDave. I had a blast to read them. Your Alien Ascension story reminded me a bit of the Alien Out of the Shadows book. You know the elements like the mining workers finding some rare material, and a ship. But I love it. Keep on the good work.
That was one reason I was a bit disappointed with Prometheus. I thought the Hammerpedes where an interesting concept and I would have loved to see more of them and be explained a bit further then only shown for a few seconds.
