Games Workshop are bringing back Necromunda, with a series of new plastic gangers to boot.
The pictures so far show Houses Escher and Goliath.
No word yet on a release date.

Huh. I thought I heard someone say Shadow War: Armageddon was basically their Necromunda reboot. I might pick this up when it comes out, but I never played the original Necromunda so I don't really know whether it's worth getting in to.
