Upgrades: Beneficial to Sentinel – 72 shown
The name of the upgrade; multiple upgrades of the same name are cumulative; exclusive upgrades affect a single party member other than Shepard; ship enhancements are special upgrades that are used during the end game sequence; DLC upgrades are only available if you have installed the relevant content
Name
The type of upgrade this is, as shown on the research menu
Type
Who or what this upgrade benefits; "Squad" benefits apply to all party members, including Shepard
Benefits
The amount of credits or minerals required to buy or research this upgrade; for upgrades that can be repeated, the cost is multiplied by the number of the upgrade being researched; thus if an upgrade costs Level × 500 Element Zero, the second upgrade would cost 1,000 Element Zero, the third 1,500 Element Zero, and so on; purchased upgrades are not counted for this purpose, so the cost is the same whether purchased upgrades are purchased before or after other research; note that it is possible to get a 1/6 discount on the price of most purchased upgrades (see shop page for details)
Cost
Indicates whether the upgrade is purchased with credits or researched with element zero or minerals; upgrades that are purchased with credits are applied immediately, while others must be found and later researched on the ship
Currency
How this upgrade becomes available; purchased upgrades do not have to be researched (the listed cost is the price to buy them), but found upgrades must be; research cannot be started until Mordin is recruited; upgrades that require a certain level of another upgrade become visible in the research list when you are one level below their requirement
