Arizona Sunshine is one of the best VR zombie shooters around. And now The Damned DLC is available to extend the story and provide more hours of the undead. It’s a standalone chapter in the FPS game, and it’s also the biggest mission in Arizona Sunshine yet.

The events of The Damned take place before the story of the original game and the additional content of the Dead Man DLC. As the publisher describes it, “players get to crawl into the skin of an all-new protagonist named Liam. As one of the few zombie apocalypse survivors, he has agreed to assist a team of US special forces on a daunting mission: reactivating a nearby, zombie-infested, hydroelectric dam. As the team sets out, terrifying events unfold without warning that leaves the player to complete their objective on their own.”

Imagine that. All of the highly-trained military personnel are unable to withstand the zombie horde. Looks like it’s up to you. The Damned DLC is out now on PlayStation VR, Oculus Rift, HTC Vive and Windows Mixed Reality.
