Squad Member Upgrades | Mass Effect 2 Wiki

Squad Member Upgrades in Mass Effect 2 can be used to improve and customize our Squad Members. Upgrades are single-use items that are immediately applied when they are researched or purchased from vendors.

When you purchase a research project, you must pay the specified amount of rare resources. You then gain the upgrade described in the research project, and the upgrade moves to the "Upgrade" section of the research Terminal.

Upgrades tied to squadmates are also unlocked after completing their loyalty mission, regardless of whether their loyalty is gained.
