Chaos Orb

The Chaos Orbs (カオスオーブ) are gem-like objects that appeared in the PS3/Xbox 360 version of Sonic Unleashed. When collected, these orbs increase Sonic the Hedgehog's/Sonic the Werehog's Experience.

Description
The Chaos Orbs resembles yellow, transparent, octahedron-shaped crystrals and comes in different sizes. When collecting a Chaos Orb, it will increase Sonic's current Experience, which then can be used on the Status Screen to increase Sonic the Hedgehog's and/or Sonic the Werehog's parameters. Once a parameter level up, Sonic's abilities will increase and he can learn new skills as well (Werehog only).

Chaos Orbs can be collected from defeated the enemies in the game, be it Dark Gaia's minions or Eggman's Robots. Upon their destruction, the enemies will release a certain amount of Chaos Orbs which can be collected by Sonic. In daytime stages, all released Chaos Orbs will automatically be collected by Sonic, while in nighttime stage, Sonic the Werehog has to get close to the Chaos Orbs in order to collect them.

The amount of Experience each Chaos Orb grants is determined by its size, meaning that the large the Chaos Orb is, the more Experience it will grant. Equally, the tougher the enemy is, the larger the Chaos Orbs will be when the enemy in question is defeated.
