Forge World has some more Chaos Marines models available to pre-order from their website.
From the announcement:
Designed by Mark Bedford and Will Hayes, the World Eaters Legion Rampager Squad contains five complete multi-part resin models, including weapons, which are packed with Legion-specific detail. Each member of the squad is presented helmetless in order to show the surgical implants the Rampagers received, and the kit also contains a meteor hammer, two Excoriator chainaxes, a barb-hook lash and a pair of Falax blades; all weapons unique to the World Eaters Legion that can also be used to build XIIth Legion characters.
These models are available to pre-order now and will be released week commencing the 1st of March.
