I have coded a simple tool with PyQt4 to get player stats of Battlefield Bad Company 2.

You can choose your platform (Xbox 360, PS3, PC) or check out global stats.
It is possible to set one playername as default, to be loaded on every startup.The statistics are cached and you can view them offline too.

If you click on the logo, the app retrieves the latest information/changelog from my server and they are also available in offline mode.

What is missing?
-autoconnection (I don´t know if i should implement it)
-detailled vehicle, weapon and achievement stats

It is available in Extras-Devel
