The upgrade and modification system for weapons changed quite a bit in Mass Effect 2.

Now, instead of having to worry about heat management, players can collect ammunition in the form of "thermal clips." Each clip has a certain amount of rounds that can be fired before it needs to be discharged. Additionally, players can no longer directly modify their weapons. Upgrades can be found either while on a mission or browsing the local kiosk at the marketplace. Some need to be researched while others are applied directly following their purchase, respectively.

Mass Effect 2 Weapons Upgrades

For convenience, we've split these up based on the type of weapon they affect. Mass Effect 2 has six types of weapons: assault rifles (AR), submachine guns (SMG), sniper rifles (SR), heavy pistols, shotguns, and heavy weapons such as the grenade launcher.
