The Particle Accelerator is shown as a gray belt with the letters "PA" engraved on it in green text.
The Particle Accelerator doubles the movement speed of the player for approximately ten seconds. This speed boost applies to anything that involves the player moving, such as firing at enemies or drowning. It also makes other Power-Ups run out twice as fast, with the exception of Orbiters and Orbit Bombers.
