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 versions; Sonic starts with these abilities in the other versions.)

Memory Shard (S06)
These allows Shadow to use his Chaos Boost technique and use different special moves. The first allows him to use Chaos Snap, the second for Chaos Lance, and the third for Chaos Blast.

Large Cannon (SA2/B)
A power up for the Volcan Cannon that enables you to break open steel containers. Without this, it is impossible to obtain the Laser Blaster.

Single-Layered Extreme (S06)
This item allows Silver to perform his Hold Smash attack, flinging multiple objects at once.

Heart of Wind (S06)
With this, Silver can teleport and avoid enemy attacks in mid-air.
