Mass Effect

Mass Effect was the very start of the trilogy about Commander Shepard in his journey to save the universe from Reapers - an old civilisation that wants to kill every possible rational being in order to prevail any wars. You play as Shepard. With flexible backstory and different classes you travel to Eden Prime with Captain Anderson and Nihlus Kryik, you and your team must discover the mystery behind the attack on the human colony. In the process, it is revealed that another Spectre, Saron, has become rogue and escapes the planet to awoke Reapers and start a full-scale war with the galaxy.
