Mass Effect is a single-player action RPG where the player controls Commander Shepard, a character whose appearance, background, and class are customizable. The gameplay combines third-person combat, character progression, and exploration mechanics. Players choose from six classes like Soldier or Sentinel, each with unique abilities and weapon proficiencies. Through gameplay, players can further specialize their class, enhancing specific combat capabilities.

Combat is central to Mass Effect, with effectiveness depending on the chosen class and weapon training. The game features a squad system wherein players recruit up to six members, each with their own skills that can be leveled up. Experience points to level up are gained through quests, combat, and exploration, allowing players to unlock and improve talents.

Exploration is conducted via a galaxy map, leading players to various planets and missions. The story progresses through combat missions, while side quests might involve item collection or interactions with NPCs. The starship functions as Shepard's base, where players manage equipment and dialogue with squad members. While many planets can be surveyed, only some are explorable, either on foot or using the M35 Mako vehicle, which is used for both combat and navigating uncharted terrains. Equipment upgrades are scattered throughout the game world or can be purchased from vendors.
