In the conclusion of the War to Take Back the Planet, Sonic is transported back to Angel Island by the Phantom Ruby. He traverses the land and finds Mighty the Armadilloand Ray the Flying Squirrel trapped within Schrodinger's Capsule. After freeing them, the Heavy Magician reveals herself to have been disguised as one of the prisoners (the one that the player did not select to team up with). She steals the Phantom Ruby, leaving Sonic and his new teammate to chase her down. The Heavy Magician gives the Phantom Ruby to the wrecked remains of the Phantom King, among the Phantom Heavies. The Phantom King then uses the Ruby to restore the Hard Boiled Heavies, leaving Sonic and his teammate to begin hunting them down in Green Hill Zone.

Making their way back to Titanic Monarch Zone, the heroes once again fight Dr. Eggman in his Phantom Egg. After defeating the doctor, the Phantom Ruby is claimed by the Heavy King as Eggman and the heroes escape. If the player manages to collect all seven Chaos Emeralds, the Phantom Ruby will instead open up a portal that begins to destroy the base. Eggman will escape in a rocket car as the heroes fall behind, the heroes will then activate their Super States and barrel past Eggman, causing him to get sucked up into the portal.

In an end credits scene, the five heroes all meet up one of Mirage Saloon Zone's ice cream parlours to relax. The heroes are then interrupted by the Heavy King, who appears from behind the bar with a large ice cream sundae. The scene freeze frames on the photo of this moment with the caption "You're Too Cool!"

Modo BIS

Encore Mode is a game mode exclusive to Sonic Mania Plus that takes place after the events of the game's Mania Mode and the conclusion of Sonic Forces, and sees the player progressing through altered Zoneswith new gameplay rules.

Encore Mode includes all the Zones from Mania Mode (except the Egg Reverie Zone) and remixes them with different color palettes. In addition, there are new areas and different object placements that makes Encore Mode appear as an expanded version of Mania Mode. New pathways make use of all of the five characters' abilities. Bosses are also now either easier or harder, and some Giant Rings have been moved to other locations. The Special Stages remain figuratively unchanged from Mania Mode's, but the artistic layouts are in reverse order, and the Stages themselves are more difficult. Also, a brand new Bonus Stage set inside a giant pinball table has been added, and can be accessed from any Star Post with at least fifty Rings. Angel Island Zone has also been added as an introductory Zone; as a result of this, Green Hill Zone is the second level in this mode instead of the first.
