First, Xfire has a game detection system that allows users to join the same game as their friends, if they have it installed. Xfire will tell you what game your friend is playing and also what server. Also, depending on the type of game, there is an option to track your kills and deaths for display on your public profile. The detection feature also tracks the number of hours that you play each game while logged on.
The main feature of Xfire is its chat system. When somebody sends you a message, rather than having to close out of your game to talk, a little window pops up in your game. Simply press Scroll Lock and X, and you can chat away with minimal game interference.
As well as text chat, Xfire has a voice chat feature, similar to that of Ventrillo or TeamSpeak. Its convenient if you want to have a conversation with a friend, or if you need to talk strategy in a game like Combat Arms with the rest of your squad.
Yet another feature is that Xfire has the capacity to take in-game screen shots. I use this all of the time in Halo to take pictures of my better scores. Recently, Xfire has added a video capture feature. Although one major drawback of this is that the videos take up an enormous amount of disk space considering the length of the videos.
On the whole, Xfire is a very useful tool and a must-have for pc gamers. It is reliable for the most part, and it is updated regularly. I've been using it since 2005 and I haven't got tired of it yet.
