| | New Zombies?
In the painting article for this month's White Dwarf, they show how to paint a zombie's face step by step. However, the zombie they show isn't anything like the current kit, and it doesn't look like it has any parts taken from other sprues. It's either a one-off sculpt, which would be odd for GW to do purely for the purpose of White Dwarf painting articles, or it's something that's been kept under the radar.
Unfortunately, I don't have a picture, since I'm not paying 11 bucks after tax for Games Workshop to advertise to me. But, if you've got a chance to page through a copy of it at the local store, or have a copy yourself, check it out and let me know what you think.
