The leaks showing off the latest upcoming White Dwarf show a Helbrute on the cover. In fact I think I like the model, but off to the side there appears to be something different. A new model, possibly even an upgrade kit for Chaos Space Marines appears to be down alongside the Helbrute with a spiked head carrying a plasma gun.
What do you think?
a big thanks to YagDaviX for pointing this out this morning.
Here are some links that still have the image up.
