In Mass Effect 3 multiplayer store, you get to purchase various packs at different prices. For instance, the Spectre Pack gives you at least one Rare item out of the 5 random items that you receive. My question is, how can I tell which weapon is rare, which is uncommon and which is common?
Basic information
There are five main categories of weapons in Mass Effect 3 plus one additional category of unique guns that are used only in special situations and can't be added to the inventory. The main categories are sniper rifles, assault rifles, submachine guns, shotguns and heavy pistols. Each group of weapons has several models and you should take some time to read about all the weapons you find or plan to buy, because they have different weight, ammo capacity, rate of fire, damage value and precision. I also recommend that you carry weapons that suite your style of play, so that you'll find each of them useful. You can change your current equipment mostly by interacting with weapon modification stations. One of the stations can be found on board the Normandy (screen above), however you may also find stations while completing main missions. This isn't the only way, because the game allows you to change weapons each time you've found a new one, so you won't have to wait until you've located a station in order to test the newly obtained gun.
A very important thing you should know about weapons is that each gun has its own weight. As a result it's recommended that you don't take all five weapons with you, because the more weight you carry the slower your active powers recharge. The game displays the power regeneration bar while changing the equipment, so you can always know how much time you'll how to wait for Shepard's abilities to recharge. It's best to maintain a positive or at least a neutral value, because most active powers which you unlock during the game are very useful and you'll want to keep using them as often as possible. My recommendation is to always have two weapons in the inventory, because the regeneration bar won't suffer too much and you'll have a spare gun in case if you run out of ammo or encounter a different type of an enemy.
A good way of resolving the 'weight problem' is to upgrade the weapons you're using and it can be done by interacting with one of the terminals found on the Normandy (screen above). The game allows to upgrade each weapon to level five (V), however if you're replaying the campaign (New Game Plus Mode) the limit is raised to ten levels (X). Each time you've upgraded a weapon you'll increase the damage it inflicts and how much ammunition it can have in the magazine, so it can make a difference on the battlefield. I don't recommend upgrading all the weapons. It's best to improve only the ones you like to have with you, because each upgrade costs credits and you'd be wasting money on something you don't necessarily need.


List of weapons
Notice! The table seen below is only about the weapons you may find during the singleplayer campaign. In the multiplayer mode (Galaxy at War) the only way to obtain new weapons is to keep purchasing crates with random equipment, hoping for good luck. The last column of the table explains how you can receive/find/buy a certain weapon.
Notice! The prices aren't displayed in all rows of the third column, because only some weapons can be purchased and the rest must be found or received while completing missions. If you don't see the weapon on the store's list make sure that you don't already have it or try visiting the same store later in the campaign (after completing one or more main quests).

Received from: Asari councillor [Normandy SR-2: Combat Information Center]

Unlocked by: Received automatically after completing Priority: Rannoch.
Open the galaxy map and return to the Citadel located in the Serpent Nebula. Dock on the Citadel and then travel to [Citadel: Citadel Embassies] floor. Your destination is the office that belonged to ambassador Udina (it's located close to the Spectres headquarters). Entire the office and listen to the conversation with the asari councillor. She will share the information about an artifact which may prove to be useful in finding the Catalyst. The artifact is stored on the asari homeworld named Thessia and you're ordered to travel there in order to meet with a group of asari scientists. You may now proceed with the next primary mission - Priority: Thessia.
Notice - If during Priority: Tuchankamission you've decided to betray the krogan and disperse the false vaccine and if Wrex is the leader of the krogan, then you will stumble upon him while trying to leave the Citadel. During a short conversation with Wrex you'll find out that he is aware of your betrayal and sadly you won't be allowed to resolve this conflict situation in a peaceful way, even if you decide to choose the special renegade dialogue option (high reputation is required). The only choice you're given at this point is whether you want to kill Wrex yourself (two renegade interrupts - left mouse button) or should someone else do that for you. Wrex's death is equal to losing all krogan war assets. You should also know that if Wreav is the leader of the krogan race, then he won't find out about the false cure and therefore you won't have to worry about meeting him and losing krogan assets.
Prizes for completing the mission:
Mass Effect Asari Weapons
- Mission unlocked: Priority: Thessia
