New Pokémon GO video explores everything you need to know about Raid Battles

In Pokémon GO, a Raid Battle is a cooperative gameplay experience that encourages you to work with other Trainers to defeat an extremely powerful Pokémon known as the Raid Boss. Before a Raid Battle begins, a large Egg will appear atop the Gym. When the countdown above the Egg reaches zero, the Raid Boss will be revealed. Before you can battle the Raid Boss, you’ll need a Raid Pass. You can get one free Raid Pass per day by visiting a Gym, but you can only hold one at a time. You can also get Premium Raid Passes from the in-game shop. Upon using your pass to join the battle, you and up to 20 other Trainers work together to defeat the Raid Boss. If you successfully defeat the Raid Boss within the three-minute time limit, you’ll have the chance to catch an extra powerful Pokémon of your own.
