Deus Ex (2000)

This is a title as revolutionary in its story as it is in its mechanics. Deus Ex has been labeled a founding father of the stealth genre, but underneath those accolades is an incredible, original story that still resonates. Thrown into a cyberpunk world, you take the role of JC Denton, a nano-augmented solider with an important mission. You must recover the vaccine for a man-made virus from a dangerous terrorist organization. The premise is simple, but the overall plot is not. Deus Ex is filled with twists, layers, metaphors and side plots. Its extensive diversions from the original path both offer variety, and gives the impression of a real story. It weaves into different paths, adapts to newly discovered information, presenting anything but a straight line from start to finish. It's a game that truly adapts to your actions, and one that will keep you invested all the way.
