Crossfire is a very funny ego-shooter. It's freeware and you only need to register on the development's homepage. You have to possibility to buy different kinds of weapons. With real money you can buy some special weapons which have for example more ammo. I like to compare Crossfire with CS, because I think Crossfire is CS for the poor. So for all who don't want to buy CS can download Crossfire. In the last time, some bugs were fixed and some new maps were added.
Graphical there is a little problem: People who haven't got a wide screen monitor can only play with 1024*768 pixels. A higher resolution isn't possible at the moment.
But the game is really funny and I can advise you to download this game.
