In zombie media terms, then, Zombies, Aliens and Guns isn’t ponderous like a Walking Dead, funny like a Shaun of the Dead or cerebral like a Last of Us. Instead, it’s a big, dumb Army of the Dead, and it will be just as forgettable once it’s over. If you like your zombie-killing easy and brainless then Zombies, Aliens and Guns will scratch an open wound.
