Equipment

Characters in Mass Effect can wear and use five major types of equipment: weapons, armor, biotic amps, omni-tools, and weapon, ammo, and armor upgrades. Equipment quality is rated in Roman numerals, I being the weakest and X being the strongest. Equipment can be found in storage containers throughout the galaxy, can be aquired after defeating an enemy, or purchased from vendor or merchant NPCs located on the Citadel, various planets, and onboard the Normandy.
