Infiltrator (The Pitt)

thumb|300px| The Infiltrator can be seen when fighting [[Trogs]] The Infiltrator is a scoped, silenced assault rifle that will be added to Fallout 3 with the release of The Pitt downloadable content pack in March 24, 2009.

It is dropped by the last enemy you must fight in the fighting arena of The Pitt, The Arena. You must fight three slaves in order to gain audience with Ashur, but you must kill each before succumbing to radiation poisoning. After defeating the third and final enemy, he drops the Infiltrator, and you get a new perk which raises your Radiation Resistance. You will also have completed a quest, gaining an achievement and experience points.

While no information is known about the type of scope and silencer on The Infiltrator, it will likely function like the Silenced 10mm Pistol in that you can shoot at enemies without alerting others. As for the type of scope, it could be anywhere from a powerful Sniper Rifle scope, to a weaker Scoped .44 Magnum scope. The new trailer for The Pitt showed off the weapon for the first time being used against Trogs. The weapon model of The Infiltrator appears to be a black version of the vanilla Assault Rifle. But visible in the trailer are port slits on the foregrip indicating it could possibly be the model for an L1A1 assault rifle, a modified custom weapon located on the Fallout3Nexus mod website.
