Niantic, makers of Pokémon GO, have announced a slew of changes for the mobile monster catching and battling experience for this summer. As we approach the one-year anniversary of the game, we’ll see a fresh take on Gyms. Later, we’ll see Raid Battles. More on those in a second.

Pokémon GO will see a rolling update today across iOS and Android that will bring changes to Gyms. Gyms will now have six permanent slots that will be filled by the controlling team’s Pokémon. Other teams will need to battle these six Pokémon in the order they were assigned in order to take over the Gym. The press release from Niantic explains the new motivation system in place.

The new motivation system introduces an interactive factor for Pokémon assigned to a Gym that will impact their potential Combat Power (CP). Pokémon defending a Gym will lose motivation over time and as they are defeated, lowering their CP and making it easier for opposing teams to defeat them. Trainers from the same team can give defending Pokémon some Berries to keep them motivated.

Raid Battles sound interesting, too. They promise “cooperative social gameplay,” and they’re due in an update slated for “the weeks ahead.” Players will be able to join up with others nearby to battle tough Pokémon known as Raid Bosses. These are timed, in-game events that will temporarily take over a Gym. Players will have a chance to get special new items and to actually catch the Raid Boss Pokémon. If you play with friends, you’ll be able to do this in a private group.

If you want to participate in Raid Battles, you’ll actually need a Raid Pass. Right, here’s the catch. You can only get one a day in gyms, though you can pay real money to buy them in packs.

Raid Battles sound like the massive events teased in this game’s reveal trailer as whole cities got together to take on Mewtwo. Remember that moment?

Will this get you back into Pokémon GO?
