Pokémon GO is hosting a Gigantamax Snorlax Max Battle Day on December 14 from 2 p.m. to 5 p.m. local time and it should be a fun quick event for anyone looking to load up on raids. Gigantamax Snorlax and its shiny form will be the stars and early previews point to solid rewards and a few event bonuses that make jumping in worth it even if you’ve caught one before. The short window keeps the pace fast so it’s a good idea to gather a group or hit your local hotspots to farm as many raids as you can.
