Nintendo revealed the first details about its E3 2018 plans, which largely focus around one intensely anticipated game: Super Smash Bros. for Nintendo Switch.

The annual E3 Direct presentation will air Tuesday, June 12 at 9 a.m. PT, kicking off the event week with a look at several upcoming games. Just as Super Mario Odyssey was the primary focus of last year’s Nintendo Direct, Super Smash Bros. for Switch will receive the most screen time during the presentation.
