Horror Vault's take

When a multinational team of explorers ventures beneath an Egyptian pyramid, they unearth far more than lost history — a hidden city that has slept undisturbed for millennia. Ancient forces stir within the darkness, and what began as a landmark archaeological discovery rapidly becomes a desperate fight for survival. The expedition must confront the terrifying possibility that the gods of ancient Egypt are not merely myth, and that disturbing their rest may have set an unstoppable catastrophe in motion.
