Mass Effect 1 classes: Soldier, Adept, Engineer and hybrid choices
Choose an original Mass Effect class and cover its weaknesses with the two companions in your active squad.
Original Mass Effect campaign, first released in 2007; this guide uses the original 2008 PC port and its publisher screenshots. Legendary Edition changes, sequels and DLC missions are outside scope.
Pick a class for the actions you want to use
Soldier specializes in combat, Adept in biotics and Engineer in tech. Infiltrator combines combat and tech; Vanguard combines combat and biotics; Sentinel combines tech and biotics. The class governs your available talents, so read it as a long-term play style choice rather than a temporary weapon loadout.
Soldier is the direct weapons option
A Soldier can train across the weapon categories and eventually wear heavy armor. That durability suits a first run focused on shooting, but the default class has no Decryption or Electronics. Bring a companion who can handle secured objects instead of discovering that gap after landing on a remote world.
Use companions to balance a specialist Shepard
Adept powers control enemies, while Engineer talents disrupt opponents and provide technical utility. Your active team is Shepard plus two companions. For example, a Soldier with Liara and Tali adds biotic control and tech support. This is a practical starting composition, not a requirement to use the same companions everywhere.
Unlock talents and specialization deliberately
Some talents require ranks in another talent before becoming available. Inspect the unlock marks before spending points across several branches. Completing UNC: Rogue VI on Luna later unlocks a class specialization choice. It extends the class you selected; it is not a way to replace that class with an entirely different one.
