On the top of that you can upgrade your weapon up to Level 5 making it more accurate, more powerful and less “capricious.”
For example, the Soldier can carry all five weapon types at once without exceeding carry weight, but only if properly upgraded to do so. Luckily, in Mass Effect 3 any class can carry whichever and however many weapon types they want. Major changes have been made in the Heavy Weapons category: now you are not allowed to equip your character with them and they can only be found as pickups during missions. Of course, it has a great number of unique guns but lots of them can also be found in the previous titles. Mass Effect 3 weapon system is an expended variant of the weapon system coming from Mass Effect and Mass Effect 2.
