The best free shooter at the moment!
While not as good as the flashy Battlefield 2 it does't really focus on that scale battles, because if you want you can play smaller maps in Counter Strike style . In my opinion this game is 10x more fun to play than the super-serious Americas Army (another free online shooter).
The graphics are neat and clean, and runs good on older PCs. The audio isn't that good, with soundeffects missing and korean voices.
Plus sign goes to the internet connection speed, very fast and easy to get in.
In summary, a very good download.
