The buzzsaw was a lot of help on that last mission.
Mini review: The game was a lot of fun throughout the 50 hours I spent with it. There was a little sense near the end that the game was overstaying its welcome, but for most of the time, I really enjoyed the game and found it hard to put down. The combat never got old. The action was almost always entertaining. There were plenty of things to do (too many, really). The progression system was somewhat flawed -- on the one hand, it was nice to get perks so quickly, but on the other, this meant I maxed out my skills well before I finished the game, which decreased my motivation to continue.
The story could've been a lot better than it was, but I don't think people play Far Cry for the story. They play it for the combat, the action, the emergent gameplay, the variety of things to do in an open world ... in that regard, it really succeeded. Had I played it last year, it would've been a strong GOTY contender for me. I'd give it a 9.0.
