In the dark, crowded basement of the Chicago Museum of Science and Industry, a cultural biologist studies the history of mankind's deadly interaction with "Xenomorphic Alien Species." But something lurks in the darkness that may make the biologist's Alien encounter far less academic! Aliens: Free Comic Book Day is the frightening prequel to Aliens: More Than Human , written by John Arcudi (BPRD, Doom Patrol, The Mask ) and illustrated by Zach Howard ( Shaun of the Dead, Year One Batman: Scarecrow, The Cape ) and Mark Irwin ( Green Lantern, Brightest Day, X-Men ).
