A user on the BioWare forums has posted an allegedly complete list of weapons and upgrades from Mass Effect 3. Though unofficial, the list appears genuine and is accompanied by a leaked screenshot of the game's loadout screen.
As you can, the screen is divided up into five slots, two on Commander Shepard's back and three on his belt. Each weapon you add to your loadout will increase the weight meter, which in turn increases the recharge time on your biotic abilities. That means that biotic-heavy builds will be greatly rewarded for bringing fewer and/or smaller guns into the field, as their powers will have a much smaller cooldown penalty.
According to this list, Mass Effect 3 will include an impressive 59 weapons, more than double the amount featured in the last game. 29 of those are brand new additions, while at least 8 will only be available as DLC.
