Heavy Weapons

Heavy Weapons are a class of weapon available to all player classes in Mass Effect 2. Rather than the universal heatsinks utilized by smaller weapons, heavy weapons consume power cells that can be found on missions. The ML-77 Missile Launcher, M-622 Avalanche, and M-920 Cain are researched within the Normandy SR-2's tech lab after the player has acquired enough Heavy Weapons ammunition upgrades; the others can be found during missions.

Heavy Weapons Models
Below is a list of heavy weapon models and their base stats:


 * Table Notes:
 * Fire Mode: Single (Single-Shot), Semi (Semi-Automatic).
 * Bonuses vs. (Armor Shields): Shields and Barrier are essentially the same thing, therefor the table only notes Shields for both.

Upgrades

 * Heavy Weapon Ammo 1 - 6 (Microfusion Array)
 * Cost:HWUpgrade.png


 * +15% heavy weapon ammo capacity


 * The power cell technology used by heavy weapons is fairly old, but can be improved by rebuilding the core with more modern components. These improvements allow standard power cells to yield more shots per power cell and allow for more total shot to be fired.


 * The 6th Heavy Weapon Ammo Upgrade is only available with the Zaeed - The Price of Revenge DLC pack. During Zaeed's loyalty mission, you must make a choice, and that determines what upgrade you receive. If you want the ammo, then save the workers; otherwise you receive an Assault Rifle damage upgrade.
