Level Up Item

Upgrades are special equipment that can grant new powers and abilities to whoever is wearing them. Unlike most items, upgrades are permanent and are not lost when a character dies.

Games with Upgrades

 * (SA/DX) Sonic Adventure DX: Director's Cut
 * (SA2/B) Sonic Adventure 2: Battle
 * (S06) Sonic the Hedgehog (2006)
 * (SU) Sonic Unleashed (Note that SU only requires you to collect them in the Xbox 360/PlayStation 3 version; Sonic starts with these abilities in the other versions.)

List of Upgrades
An X means the upgrade is in that game, two Xs meaning it is mandatory to complete the game.
