Valhalla. Once a posh hotel frequented by celebrities, politicians, and wealthy businessmen, it was a towering oasis in the heart of the city. But there's been a change in management. In a city overrun by zombies, Valhalla has become the city's last stand against the undead. Gunfire has replaced calm lobby music, and red carpets by barricades and barbed wire. A different sort of clientele is queuing up, and it's for the eat-all-you-can buffet inside.
