Quake 4 really delivered on all fronts for me in terms of purely frenetic gameplay. I jumped at the cutscenes, I cried out expletives when I was getting owned by the Strogg, I gasped when the storyline took a major plot twist, and I was moved by the stunningly beautiful graphics. Quake 4 is An addiction, a perfect sequel, both in story and gameplay, and a game you will want to explore over and over.
