Everything was going just fine. We touched down on the asteroid to investigate the weird monolith we found there. They came out of nowhere – one moment, nothing, the next, these space-spider things are everywhere, a whole swarm coming right at us!

A cartoon: a grey, crater-pocked  surfact, with lots of blue spider-liike creatures crawling toward the viewer, and in the background is a sort of grey tower with a round bit on top.
