Awesome / Sonic Chrono Adventure

• When Eggman manages to take over Sky Empire with the magnetic energy he amassed, the real Dr. Ucano isn't allowing that to continue as he not only shows up right away and leads civilians away from the city, but he unlocks the three power sites in Sky Speedway Zone to let Sonic disable the power supplies run into the city, preventing Eggman from getting any more stronger. Dr. Ucano notes that, by doing so, the Sky Empire, his greatest creation, may slowly plummet to South Lakes due to power failure, but he disregards that in favor of the civilization. And then, as Sonic races through Sky Speedway Zone, the Awesome Music of Ace Combat Zero: The Belkan War rolls in, all tracks signifying the decisive moment.
• The final boss uses "It Has to be This Way" from Metal Gear Rising: Revengeance.
• The ability to perform a Boost in a Classic-era Sonic game.
