While its intended design is for deep space construction, the concentrated laser beam of the Spectra is highly effective against organic and synthetic enemies.
The Spectra is a Corpus pistol unlockable through Energy Lab Research in the dojo. Released in Update 9, it appears to be a handheld cutting laser that (according to its description) is as effective at cutting flesh as it is at cutting metal. It is essentially a sidearm version of the Flux Rifle, with the focus on puncture instead of slash damage.
The Spectra's beam has a maximum length of 15 meters (compared to the Flux Rifle's 25 meters) and approximately five seconds of firing time before the cell runs dry.
The beam of the Spectra acts similarly to the Scorpion's grappling hook, as the beam requires some time to reach its maximum range. This expends Spectra's ammunition in the process.
Ceasing fire from the Spectra actually retracts the beam.
Very useful with Volt as his Electric Shield can give the spectra infinite range, with added electrical damage.
Similar building with the Flux Rifle, adding Magnum Force to the Spectra in order to provide inaccurate results can actually be beneficial, as the shooter does not require precise aiming. This will further reduce its medium range effectiveness however.
The Spectra is essentially a smaller Flux Rifle -- dealing as much damage as the Flux Rifle did on release, albeit with shorter range and reduced ammo capacity.
Spectra is the plural form of spectrum, which essentially means "range".
During the final phases of the Arid Fear event, the corpus scouts were equipped with Spectras, which they would use for short durations before attempting to run.
