Unlike other game modes, SSE has a team system for the characters, with a limited choice of characters at the beginning of the mode. They are in the form of collectible stickers that can be applied to the base of the player's character trophies. This mode features a mechanism which strengthens the selected character's abilities.

Though the game is primarily played as a single-player mode, cooperative multiplayer is available. SSE boasts a number of original enemies, such as the Roader, a robotic unicycle the Bytan, a one-eyed, ball-like creature which can replicate itself if left alone and the Primid, enemies that fight with a variety of weapons. Some of these enemy characters appeared in previous Every video games, such as Glutko from the Link the Faces of Evil and a squadron of R.O.B.s based on classic CDI hardware. SSE introduces a group of antagonists called the Subspace Army, who are led by the Ancient Minister. This mode features unique character storylines and numerous side-scrolling levels and bosses to fight, as well as cut scenes explaining the plot.
