Weapons
Few weapons have been confirmed for Mass Effect 3 beyond the bonuses found in the Collector's Editions.
Bioware has also confirmed that any weapons Shepard acquired in Mass Effect 2 will carry over to Mass Effect 3, and this includes weapons added by the Firepower pack DLC.
In previous Mass Effect games there have been a few categories of weapons to choose from. The type of weapon you are able to use depends upon the class you choose to play as or the unlocks that you choose in the story. The main weapons used by Shepard and his crew include heavy pistols, assault rifles, shotguns, sniper rifles, grenades, heavy weapons, and sub-machine guns. Each weapon is chosen from the weapon wheel. You can only switch between the weapons that you have unlocked and equipped.
Below are many of the weapons Shepard used in Mass Effect 2.
