When you embark on the Suicide Mission, it's with the knowledge that literally anyone, even Shepard, can die. Its stakes are the secret to its success. Where most triple-A games run out of gas by their midpoints, Mass Effect 2's story reaches a crescendo when you dive through the Omega 4 Relay for the final mission. The entire game is spent building to the moment that you take the plunge and bring the fight to The Collectors-a powerful race with mysterious motives. In many respects, it is a master class in how to bring a massive game to a satisfying conclusion. Much as everyone argues over Mass Effect 2's relative merits, I think almost everyone can agree that, final boss notwithstanding, its grand finale is amazing.
The Mass Effect Trilogy has many outstanding moments, but one stands head and shoulders above them all: The Suicide Mission.
