The sleek lines of the Detron conceal its ferocious nature. The hand cannon's semi-automatic action takes down enemies with speed and efficiency.
The Detron was one of two rewards for The Gradivus Dilemma event, the other being the Brakk. While it was not awarded from the event, as the Corpus lost the conflict, its blueprint and components are now dropped by the Harvester.
This particular damage combination is also effective against Ancient Infested (as the Corrosive and Blast Damage will make short work of Disrupters and Toxics, while the Radiation Damage will do more damage to Healers).
Colloquially, a "hand cannon" often refers to an extremely powerful pistol chambered for a high caliber cartridge such as .500 S&W Magnum or .50 Action Express.
In Livestream 17, the developers jokingly claimed that the Detron pistols intended as rewards for the Gradivus Dilemma were "melted down and used to make MOAs." This has more or less proven to be true, as the Harvester drops the Detron blueprint and parts.
Like the Flux Rifle, the Detron does not follow the Corpus weapon naming convention.
During the reload animation, A pack of 6 energy cells (presumably) is ejected from the gun, although, the Detron only has the capability of firing 5 rounds before reloading.
The Detron had an entry in the Codex shortly before players could actually obtain it (at the time, the Harvester dropped nothing upon defeat).
