After consultation with Dave Drake, author of the Hammer's Slammers series, a range of humanoid lizards called Molts are now available from Ground Zero Games. In 28mm (although as they are shorter than humanoids, they stand around 25mm tall), these creatures (from Drake's story At Any Price are one of the few aliens featured in the military SF classics.
They are primitive teleporting peoples who fight using hit-and-run tactics and found weapons, and will be featured in the upcoming release of the Hammer's Slammers tabletop gaming system - Hammer's Slammers: The Crucible by Pireme Publishing.
A pack of these, sculpted by the talented Martin Baker, will feature eight figures: one Leader with a close-combat blade (and larger horns as befits his age); and seven younger Hunters, Warriors and Adolescents armed with combat shotguns (2), powerguns (4 in two different poses), and 1 with an RPG or 'Buzzbomb'. The sample pack shown was painted by Kevin Dallimore.
