Pokémon GO, the augmented reality mobile game from Nintendo and Niantic Labs, is rolling out today on Android and iOS devices.

The game is currently not available in the US, but is expected to be at some point today.

Pokémon GO is a similar game to Niantic’s previous title, Ingress. Players can capture, train and battle Pokémon that they find in the real world—essentially bringing the core concept of Pokémon games into an augmented reality, global battlefield.
