Finnish game developer Next Games and AMC have released a gruesome new mobile game that uses augmented reality (AR) to spread zombie hordes through the real world. The Walking Dead: Our World, first announced in August 2017, is available to download free for iOS and Android, and invites you to fend off walkers solo, or in weekly team missions with friends. 

The Walking Dead: Our World is powered by Google Maps, with a game map that landmarks like the Statue of Liberty, the Burj Khalifa and the London Eye. Think Pokémon Go, but with gruesome, bloodthirsty walkers to battle instead of bouncy little critters.
