The Mara Detron can be purchased from Baro Ki'Teer in the Concourse section of the TennoRelay for 200,000 200,000 and 500. Note that Baro Ki'Teer's stock changes with each appearance, and this weapon may not be available on a succeeding appearance.
The Mara Detron's increased fire rate means that mods like a capped Lethal Torrent make it fire faster than can be clicked. Giving the fire button a secondary binding to the mousewheel can alleviate this.
As the Mara Detron is essentially an improved Detron, refer to the Detron's Tips for more upgrade/optimization possibilities.
The Mara Detron can be visually identified from the standard Detron by the diffuse cloud textured animation on its body.
This animated texture is based off the weapon's energy color, and thus can be changed to match any hue the user wishes for.
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.
The Mara Detron ejects its magazine when reloading.
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.
Mara is a Hebrew female adjective, meaning bitter.
This is currently the first and only Mara-type weapon.
