It may have been around a few years now but has set up a beta for Team Fortress 2 in order to test their continual updates and improvements.

The beta test is akin to the Public Test Realm on and is essentially a place where Valve can mess around with the game to see what works without breaking the experience for players.

Possible uses for the beta test are "testing and tuning various class, item, and weapon changes... map changes and variants... [and] new technologies without the risk of breaking the game."

More details can be found on the Team Fortress 2 blog as well as an FAQ and if you want to get involved buy a copy of the game on and download the beta as well.

Thanks 1UP.
