No, we haven’t gone back in time. Valve has just launched a new open, public beta for Team Fortress 2 just over three years after its release. The move is similar to that of the Football Manager Live beta. Valve will use the beta to test class, item and weapon changes “without the risk of breaking the game”. Also expect some “higher level, game-wide experiments” to contend with too.
“As you’ve probably seen by now, we like to change things in Team Fortress 2,” Valve said. “A lot. And while we’re perfect most of the time, we occasionally get something wrong. One reason for this is we just don’t get enough data from internal play testing, and another is that we spend too much time watching Tom Bui serenades on YouTube.”
To gain access to the beta, launch Steam, open the Library and install the “Team Fortress 2 Beta” from your games list.
