SPD

SPD is a game mechanic that appears in the Xbox 360/PlayStation 3 version of Sonic Unleashed. It is a speed measurement used to rate Sonic's velocity in daytime Action Stages.

Overview

Whenever Sonic passes a Star Post during daytime Action Stages, the checkpoint will clock how fast Sonic is going and measure his velocity in SPD.

Trivia

It is unknown if "SPD" is an abbreviation of the word "speed", a recurring measurement for velocity in the Sonic Riders series, or an acronym.
