Valve has announced that Steam will now officially support free-to-play games featuring microtransactions - a feather that had previously been missing from the digital store's hat.
Five games have been launched on Steam in time with the announcement - Champions Online: Free for All, Forsaken Worlds, Spiral Knights, Global Agenda: Free Agent and Alliance of Valiant Arms.
Each of the five initial free-to-play games will feature exclusive content, says Valve, which will be unveiled through a new 'F2P Games of the Day' slot which will cycle until Saturday.
'The introduction of Free to Play games is another example of the constant evolution of Steam,
' said Valve's Jason Holtman in an official statement.
'Free to Play games offer new game genres and game experiences for customers, while offering developers and publishers new revenue opportunities and the ability to reach customers in areas of the world where the traditional packaged goods model is less popular than F2P.
