The historic foundation of the ultimate space-opera. The original Mass Effect couples deep RPG inventory customization and low-gravity planet Mako exploration with a legendary narrative dialogue wheel that changes the galaxy.

Mass Effect is a historic, highly influential sci-fi action-RPG that laid the foundation for one of the greatest space-operas in entertainment history. You play as Commander Shepard, a human soldier seeking to stop a rogue Spectre named Saren and his army of sentient machines. The gameplay merges third-person tactical shooting with deep RPG customization: players select from six classes, distribute talent points across extensive skill trees (unlocking biotics and tech decryptions), and customize weapon heat-sinks, armor mods, and ammunition types. Traversal is split between walking massive hubs like the Citadel, piloting the Mako vehicle to explore rugged, low-gravity planets, and managing crew conversations on the Normandy. The game's primary mechanical signature is the dialogue wheel: players select Paragon (noble) or Renegade (pragmatic) options that actively shape the galaxy's political future.
