Gameplay
An space-based action RPG like its predecessor, gameplay in Mass Effect 2 revolves around the player's particular version of Commander Shepard and continuing development of this character as the game proceeds. As the game opens a variety of character classes are made available to the player, with talents, both exclusive and general, associated with each. With experience these talents are leveled up, resulting in the unlocking of related abilities and/or entirely new talents. The player has the ability to customize their Commander Shepard in a number of ways including physical appearance, gender, and certain aspects of their personal history, with the rub being that these choices can influence things like available missions, dialogue choices with non-player characters (NPCs), and character background.

Accompanying this main character are a number of preset supporting characters that the player can direct and develop relationships with, which again, will alter the outcome of the story. All the characters from the original game make an appearance in Mass Effect 2, but the immediate characters surrounding Commander Shepard are new. Additional new features that players can expect to experience include new alien races; a more realistic damage system; a new heavy weapons system allowing for maximum damage; a regenerative health system; a dramatic increase in the number of character animations available to Shepard; and updates to the dialogue mechanic used when conversing with NPCs.

Integration with the Original Mass Effect
Mass Effect 2 allows players of the original Mass Effect game to import save games to continue the story of their own Commander Shepard. In doing this, the decisions that were made in the first game will affect the events of the second game. In addition, characters from the first game will return, as long as they were not killed off by the player in the first game. On the other hand, new players coming to the series for the first time in Mass Effect 2 will start a brand-new character, discover the events of the previous games as they progress and embark on a thrilling stand-alone adventure that does not require the previous game for play.
