Pokemon Masters' first Legendary Arena launches today, serves up the game's biggest challenge to date

Pokemon Masters' first Legendary Arena has kicked off today, serving up what is perhaps one of the game's biggest challenges to date. In this mode, you'll battle against powerful legendary Pokemon using only a limited number of sync pairs.

The damage you deal to them will carry over to the next round, though they're all said to have giant health pools, so expect to have to chip away at them for a fair while. The longer nature of these battles means that you'll have to pace yourself well and strategize at every turn.

The first Legendary Pokemon you'll face off against is Entei. This battle will be available until June 24th, giving you around two weeks to get involved. Anyone who has progressed beyond Chapter 2 of the main campaign can try their luck against him.

Several other additions have also arrived today, including the ability to display your medals on your in-game profile, new sync pair Sygna Suit Grimsley & Sharpedo, and a new story chapter featuring Grimsley.

Pokemon Masters is available for download now as a free-to-play game from over on the App Store and Google Play.
