Super Smash Bros. Invitational 2018 featured the unreleased Super Smash Bros. Ultimate title on Nintendo Switch.
There were a total of eight players who will be competing at this invitational. An even mix of Melee and Smash 4 players were invited, with ZeRo, MKLeo, Abadango and Mr. R primarily being known for the latter title, while Armada, Mango, Plup and Lucky are better known for Melee.
This version of Smash Ultimate is the E3 2018 build of the game, so there are only about 30 characters available out of the 65 currently announced. According to Sakurai, the pro players have had very little time with the new game before this competition got started.
