Nintendo held its press event at the annual E3 2018 video game trade show by showing footage of Super Smash Bros. Ultimate, and shared details about the latest entry in a series with sales of more than 40 million units worldwide.

A new game built for the Nintendo Switch system, Super Smash Bros. Ultimate lets up to eight players square off in action-packed battles that are all about smashing beloved video game characters off the screen.

Super Smash Bros. Ultimate will include every single fighter ever featured in the series' nearly two-decade run, making it one of the biggest crossover events in gaming history. Fans can enjoy returning favorites like Ice Climbers and Pokemon Trainer, as well as newly announced fighters like Ridley from the Metroid series and Inkling from the Splatoon series. The game supports a variety of controller options, including Nintendo GameCube controllers (original or newly designed), Joy-Con controllers or the Nintendo Switch Pro Controller. With Nintendo Switch, players can throw down whenever and wherever they like in Handheld or Tabletop mode while enjoying online play.

Super Smash Bros. Ultimate combines many stages and new items, with gameplay that makes it easy for players of all skill levels to jump in. All current Super Smash Bros. series amiibo figures are compatible with the game, and any fighter's amiibo figure from other series will also be supported. Super Smash Bros. Ultimate is set to launch on Dec. 7, exclusively for Nintendo Switch.

Nintendo also announced that Fortnite is available for Nintendo Switch - today. Players can download it for free from the Nintendo eShop, then test their mettle in thrilling crucibles of combat.

Nintendo will also give attendees of E3 the chance to play Pokemon: Let's Go, Pikachu! and Pokemon: Let's Go, Eevee!, two Pokemon games launching for the Nintendo Switch system on Nov. 16 at a suggested retail price of $59.99 each. The games offer a new way to experience Pokemon that lets players adventure with their partner Pokemon in the vibrant Kanto region, discover fresh and exciting Pokemon encounters and Trainer battles, as well as share the adventure cooperatively with a friend anytime, anywhere on one Nintendo Switch system. Players can even transfer Kanto region Pokemon into the game from the Pokemon GO app. These games serve as an entry point to the Pokemon series for newcomers, but they also provide fun and engaging experiences for Pokemon fans of all ages. A new accessory, called Poke Ball Plus, comes with Mythical Pokemon, Mew and is sold separately from the games. Poke Ball Plus includes a pressable analog stick and button, so players can control the new games entirely with the accessory, if they want. Nintendo is announcing two bundles, in which players can get Pokemon: Let's Go, Pikachu! or Pokemon: Let's Go, Eevee! with one Poke Ball Plus at a suggested retail price of $99.99 each.
