Power Shield

The Power Shield is a power-up that appears in the PlayStation 3/Xbox 360 version of Sonic Unleashed. It can only be used by Sonic the Werehog. When the player obtains a Power Shield, Sonic the Werehog's defense will take less damage for a short time.

Description
The Power Shield resembles an aqua green kite shield with a golden frame and a golden gem-embedded rhombus on the middle of the front surface. When touching the Power Shield in gameplay, Sonic the Werehog will glow with an aqua green aura and any damage he receives from enemies for a limited time will be significantly reduced, meaning his Life Gauge will be depleted less than normal when attacked.

The Power Shields can only be found in the game's Nighttime Action Stages, where they are hidden inside breakable objects throughout the Acts. To find them, the player has to hit and destroy the breakable objects.
