The Phazon Enhancement Device is based on captured Space Pirate technology. It was being tested by a GF Marine battalion stationed in the Norion System. At some point the Space Pirates developed a version of the system and applied it to a large number of their troops. Marines can initiate an energy siphon from the supply of Phazon carried in a backpack into their armor suits. This allows them to temporarily enhance the exoskeleton and weapons systems of their armor suits. To date, no Marines have displayed signs of Phazon Sickness, common in subjects who use the Space Pirate's version of the system. The PED is represented by a silver plate with the GF logo and some markings on it which attaches to the owner's armor (or, in Gandrayda's case, to a necklace-like object worn around the neck).
