CastleMiner Z review. Classic Game Room presents a CGR Undertow review of CastleMiner Z for the Xbox 360 developed by DigitalDNA Games for Xbox Live. In CastleMiner Z, players mine resources to create shelters and weapons, defending themselves from hordes of enemies—from zombies to dragons! Like Minecraft, all the tools you'll need must be crafted from the resources around you. But when zombies are coming from the ground, that's easier said than done. This video review features video gameplay footage of CastleMiner Z for the Xbox 360 and audio commentary from Classic Game Room's Derek.
