Player can now pick up weapons from dead enemies.
Weapons are no longer limited to certain classes. Instead, each class will have a limited number of slots to carry weapons, and Soldiers will be able to carry all of them at the same time.
After being in absent in the second game, weapon modifications will return in greater depth. Players can now customize different parts of their weapons, such as their scope and barrel, but it's unconfirmed whether ammo types, such as Corrosive Rounds from Mass Effect 1, will make an appearance.
Like weapon modifications, grenades will be returning with a more round, realistic shape and a shorter detonation time.
Guns that were picked up in Mass Effect 2 can be used in Mass Effect 3.
