Good, but too short.
Great game but a little short. However, you will probably want to play it through more than once. It is a lot like other 1st person shooter games, but they have some RPG elements and a nice variety of enenmies so you are not shooting the same old poeple. Storyline takes a bit to appear but throughout most of the game you are left wondering, who are the Authority? Also, people who complain about having to do a mission all over again, you can save at lots of different points in the game and can save at anytime during most missions so you don't have to start them again. The minigames are fun (never seen five finger fillet done like this before) and there is a good, but small variety.The major downside of the game is that single player only lasts about 10-20 hours but there is still an online with co-op and competitive gameplay.
