Watch Dogs: Legion of the Dead (Ubisoft)

London has fallen. The streets are plagued with mindless hordes of the undead. Communication with the outside world has been cut off. Is it some experiment gone wrong? Is this nature's wrath on humanity? No one knows why the dead will not rest... Only days after the first sightings, the streets of London have become overrun with the living dead. Albion soldiers have barricaded themselves to protect their few remaining supplies. In a desperate measure, the government has deployed autonomous drones to eradicate the unimaginable horrors roaming the streets.
