The cover for Scott Sigler’s Aliens: Phalanx is out now! You can see it is the tail of an Alien piercing what looks like a knight’s helmet. Some other people had their own interpretations.
I think some were hoping it would connect to Sigler’s exisiting works but he clarified they do not, but revealed it follows on from Alien and Aliens.
Despite the helmet the story doesn’t contain any knights.
