New Gameplay Trailer for Pokémon Masters Details Cooperative Play, Pokémon Masters League, and More — Game Planned to Release in Summer 2019

Today, DeNA Co., Ltd. and The Pokémon Company revealed more gameplay content and features for Pokémon Masters in a new trailer for Pokémon Masters, a real-time strategy and battling game for compatible Android and iOS devices that is planned to release in Summer 2019.

• Cooperative Play – Join two players from around the world for three-player co-op against AI opponents. Work together to unleash the unity attack, a special coordinated attack from all three sync pairs (a sync pair is the combination of a Trainer and their partner Pokémon).
• 3-on-3 Real-Time Battling System – Witness the thrill of the 3-on-3 real-time battling system. The trailer offers a look at Trainers teaming up with their partner Pokémon to unleash powerful sync moves.
• Pokémon Masters League – Compete in the Pokémon Masters League tournament, which features 3-on-3 battles that take place only on the artificial island of Pasio. In this tournament, Gym Leaders, Elite Four members, Champions, and all-stars from every region of the Pokémon world have formed sync pair teams. Players will battle these teams all across Pasio to obtain badges and become champion of the Pokémon Masters League.
• Sygna Suits (not pictured in trailer) – Special outfits that Trainers can wear into battle. When Trainers wear a Sygna Suit, their partner Pokémon changes to match. For example, when Brock dons his Sygna Suit, he teams up with Tyranitar instead of Onix.
