XR-42 Phoenix

The Pheonix is an incredibly advanced human weapon, made with reverse-engineered Chimeran technology, and only appears in the Co-op campaign, and only with a Medic. The weapon is named after the legendary Pheonix bird, which is said to die in flames and is reborn from the ashes left behind.

The Pheonix fires a beam of energy which, upon contact with a Chimera, drains the target's energy-rather slowly. This energy can then be fired at a human ally to regenerate their health.

The Pheonix cannot drain human energy, and cannot heal a Chimera. How this is possible is unknown.
