Some Pokémon Go players can now start working in groups to take on powerful creatures in Raid Battles, one of the long-awaited features for the popular augmented reality game. There's a catch, though: Pokémon trainers have to be level 35 and up to access the new co-op mode, so don't get too excited if you're a noob. In addition to that, developer Niantic says the Raid Battles are only live at "select" Pokémon Go Gyms around the world, though it's unclear which exactly. Those of you who do happen to be near one will have the chance to capture rare Pokémon and unlock a handful of other rewards, such as Rare Candies, Golden Razz Berries and different types of Technical Machines.
