Players of Valve's multiplayer shooter Team Fortress 2 will notice a few odd things if they play the game at a certain time period on Tuesday. The game's official web site has announced that from 4-5:30 pm Eastern time on Tuesday a number of features in Team Fortress 2 will be unavailable due to maintenance.

While the game itself will still be working, certain elements like crafting, trading, backpacks, loadouts and the in-game Mann Co item store will not be working during the maintenance time period. There's also some changes being made for the third party developers who are working with the Team Fortress 2 Item Web API.
