The Mara Detron has a distinct sound when fired, closer to traditional shotguns than the energy-based weapons regularly used by the Corpus.
Despite being from the Orokin Era, it does not appear to be manufactured by the Orokin. As a smuggler's weapon, it may be implied this weapon was designed outside of their authority. It might similarly be speculated this could be a clue to the very early origins of the Corpus.
Mara means Bitter in hebrew.
Unlike the standard Detron, the Mara does not eject its power cell/magazine when reloading. This may be a bug.
The flowing effect on the weapon is similar to the flowing effect on Steam's Phased Skins promotional items.
The Mara Detron was leaked as an entry in a player's Profile under Equipment, along with the Imperator Vandal, before it was revealed to be sold by the Void Trader Baro Ki'Teer.
