Yesterday, Valve put up a new blog entry detailing some of the new features that have been added to the Steam Controller in recent weeks. In doing so, they also revealed that over 500,000 Controllers have been sold.

Some of the latest features are also pretty nifty, including the fact that more and more games are supporting the Steam Controller right at launch and that you can edit your Steam Controller configurations without having to pop into Big Picture Mode.
Play more new games out of the box
Developers are now fine-tuning their games to work great with the Steam Controller at launch. Recent examples include DOOM, XCOM 2 and Dark Souls III, and more are coming soon.

Same experience from desktop to couch
You can now configure and use the controller from your desktop, including the pop-up keyboard to communicate with your non-Steam programs.

Rumble Pass-Through
The Steam Controller can now use its Force Reactors to capture and reproduce the rumble effects from your favorite games.

Tune once, play anywhere
Create templates from your favorite settings and apply them across all your games.

Uninterrupted action Works great with any game Steam VR Support
Full Steam Controller support in VR Game Theater mode, including using the motion controls as a steering wheel.

Coming soon: Even more configuration power
You will soon be able to use Activators to assign actions to press-and-hold, double click, toggle and more. For example, in DOOM you can cycle through all weapons by pressing a button or double tap it to bring up your BFG.

Valve has also cut the price of both the Steam Controller and Steam Link by 30% in the Steam Store and through select retailers. That brings both devices down to $35 (USD) each instead of the normal $50 price. This offer ends on June 6.
