Garvin Quinn

Garvin Quinn was the engineer on the Rifleman Bank Station in Deus Ex: Human Revolution - The Missing Link, and functioned both as a merchant and Netanya Keitner's contact.

Biography
After an indeterminate time working under Janus, an agent identifying as "no1" was eventually chosen to infiltrate Belltower's ranks as a low ranking Irish engineer named Garvin Quinn, with the intent of damaging their reputation. He then eventually approached Lieutenant Commander Netanya Keitner, the second in command officer on the base, and recruited her to gather incriminating evidence under the guise as an Interpol agent.

Upon Adam Jensen's discovery and capture by Pieter Burke, Quinn saw an opportunity for the use of a neutral pawn in his plan, and ordered Keitner to release him. After guiding Jensen to a meet up point with Keitner, he eventually met Jensen in person (under his engineering guise), and provided him with supplies. After Jensen required an optical augmentation modified to reach the lower labs, Quinn used his engineering skills to assist him.

After the base was placed on high alert and Keitner was killed, Quinn contacted Jensen wishing him good luck and telling him he left some supplies in his now unlocked shop. Contrary to what he said, however, Quinn actually remained on site to communicate with an unknown superior and to prepare for Jensen's success.

Upon Pieter Burke's neutralization, he then revealed his true affiliations and motivations to Jensen, before rewarding his work by transporting him to a second ship heading straight to Omega Ranch. After Jensen's departure, he can be heard discussing Jensen's potential with Janus, before being dismissed due to Jensen's obsession with Megan Reed.

Quinn's Shop
Quinn offers only a few of the bare essentials in his shop, such as hypostims, Cyberboost Proenergy packs and jars, and a surprisingly large number of beers. Additionally, he has in stock a small number of ammunition packs for common weapons, like the 10mm pistol or shotgun, but also for the Typhoon Explosive System, and a couple of rockets. He also sells one praxis kit.

If the player successfully completed the Acceptable Losses sidequest, Quinn will offer a 25% discount on all items. Another 25% discount (for a total of 50%) can be gained if the player uses the CASIE augmentation and chooses the "Pressure" (Omega) option. Alternatively, using the "Appease" (Alpha) option increases Quinn's stock with items "reserved for another customer" (sic). These additional items are:


 * 2x Stun Gun darts
 * 2x Rockets
 * 4x Heavy Rifle Ammo
 * 1x Laser Targeting System
 * 1x Target-Seeking System
 * 1x Silencer
 * 2x Praxis kit (Make sure to buy the original praxis kit first in order to get 3 total, otherwise one is lost)

The additional discount or the increased range of goods can be gained even if the player acquires the CASIE augmentation after having talked to and bought items from Quinn already, and as long as he is still in his shop.
