I was lucky enough to get one of these bad boys prior to release. This is an amazingly nice kit. Everything fits together very nicely, clean mold lines and it slides right into a chimera chassis to make a IG Medusa.
It will also work as a stationary siege gun and comes with a set of sand bags for this exact purpose.
Here are the kits contents:
This is a mock up of the kick in a chimera chassis. Slides in just like the Basilisk.
This kit should be for sale in early Dec so keep your eyes open for it.
