Nintendo just dropped their final pre-launch Super Smash Bros. Ultimate Direct, and, in addition to learning about three new fighters (more on them here) we received a ton of info on the game’s mysterious Spirits Mode, surprise Adventure Mode, and more! If you’ve got 40 minutes to spare, you can check out the entire Smash Bros. Direct, below.

Spirits Mode looks to be the real meat-and-potatoes of Smash Bros. Ultimate. Basically, players can unlock “spirits” based on a huge array of minor characters not important enough to qualify for full fighter or Assist Trophy status. You can then equip a combination of these spirits to the fighter of your choice, giving yourself a variety of stat and ability boosts. You can check out a video intro to Spirits Mode below (thanks to GameXplain for capturing these individual bits from the Direct).
