Dr. Eggman's plan had been foiled once again, but the evil doctor vowed to return, more determined than ever. Sonic.exe and Sonic parted ways, the former returning to the digital realm, ever vigilant, while the latter continued his quest to protect the world from threats both human and supernatural.

In Round 2, players took on the role of Sonic.exe and Sonic as they sprinted through an ever-changing, nightmarish world. The stage was filled with hellish creatures, such as demonic imps and ghostly apparitions, all trying to halt their progress. The pair's skills complemented each other perfectly; Sonic.exe could manipulate digital constructs and traverse code pathways, while Sonic could use his speed and agility to overcome physical obstacles.

As they approached the end of Round 2, Dr. Eggman revealed his latest creation: a massive, hellish golem fueled by the chaotic energy of the Spirit Realm. The golem was nearly invulnerable to conventional attacks, and it seemed that Dr. Eggman's plan was about to come to fruition.
