Bioware has released a new marketplace on additional content for Mass Effect 2 called "Firepower" adds three new weapons that you can find the armory of Shepard. The first of these is the Phalanx gun of that power of a laptop with a laser pointer, the heavy gun Mattock is instead a hybrid between a sniper without a scope and an assault rifle with no recoil and the last weapon is a shotgun Plasma Geth. The package is downloaded from the web as always at this address at a price of 160 Microsoft Points.
