As I've not yet finished Halo 2, and with work and the holidays I'm not sure when I will, I've decided to review Halo 2 in pieces rather than as a whole, logging my impressions of the game as I play through it. The Halo 2 Impressions page will break the game down level by level; it won't be completely a review, nor completely a walkthrough, and one of the major points of emphasis will be comparison and contrast to Halo 1 and Marathon. So far there are three items in the Halo 2 Impressions section: The Heretic, Armory, and Cairo Station.
