"It's some kind of energy sword prototype... Looks useful."
"You should let me examine it."
"Of course. After some field testing..."

- Nova and Reigel upon the former's discovery of the blade(src)

Nova wielding a monomolecular blade

The monomolecular blade is a prototype terran energy sword.


Monomolecular blades utilize the wielder's psionic energy to further hone an edge that has already been sharpened to a microscopic degree, allegedly only one molecule thick at the edge, allowing it to cut through both physical armor and energy shields.[1] The blade's color shifts depends on its user—blue for ghosts, red for spectres.[2]

A monomolecular blade was discovered in a Defenders of Man facility on Tarsonis by Agent Nova Terra. Nova then used the device to aid her in maneuvering through the facility undetected.[1] Later, renegade spectres from the secret Tartarus lab also used monomolecular blades after stealing the Griffin, and utilized them in their battle against Nova and her dark templar allies.[2]

Game Effect[]

The monomolecular blade is a choice for Nova's weapon slot in Nova Covert Ops after completing "Enemy Intelligence."[1] When playing as Nova in Co-op Missions, the Holo Decoy summoned by her will wield the Monomolecular blade, and is able to use its associated Dash Attack.
