Mass Effect 3: How to Unlock Weapon Capacity Upgrades in Multiplayer
In Mass Effect 3 for the PC, PS3, and Xbox 360, unlocking weapon capacity upgrades to use in multiplayer games is based on a card system. You earn points to buy card packs (or you can use real money if you’d like), open the packs, and you get to use whatever you get from those packs when you play online.
Weapon capacity upgrades only come in common and rare form, so you’ll need to purchase recruit and veteran packs to get all of them.
