GameXplain: Portal 2 Review

GameXplain Says: "Portal was one of 2007’s greatest surprises. Not only did it offer a ground-breaking and mind-blowing experience, it did so in style, offering a script still quoted (some might say excessively) today and one of the most memorable characters this side of the 16-bit era. Rather than deliver an incremental sequel, ala Left4Dead 2, Valve has spent the last four years building, refining, and polishing their follow-up to this amazing title."
