After months of waiting, Valve has released its first piece of hardware since the Steam Deck OLED: the Steam Controller, a gamepad that takes the versatile mix of inputs from the best handheld gaming PC and lets you play games on your TV using any device that runs Steam.That includes gaming PCs, Macs, Steam Decks, and, one day, the Steam Machine and Steam Frame.

But the Steam Controller is releasing ahead of the latter two devices, and into a market where Xbox controllers dominate gaming on the couch. Even Sony's DualSense controllers have great support on a PC. But, according to Valve, they don't match what you can do on the Steam Deck, and they say people want that.

Building the Controller

"We got some feedback that while they really appreciated having the same exact experience with respect to the UI and being able to get in and out of their games quickly and all, that docking a Deck meant missing some of the inputs, right?" said Griffais. "And so I think the Steam Controller is a great experience for that. You have all the same inputs that you're familiar with. It's pretty much the exact same layout as the Deck, with a bunch of improvements on it, but also just for, you know, just PC as a whole. "

Among other controllers, like what you get from Xbox and PlayStation, the Steam Controller sits in a sort of middle ground. It has more features than a standard Xbox controller, for instance, but doesn't have the physical customizability — think replaceable thumbsticks and hair-trigger locks — like a more expensive Xbox Elite Controller or PlayStation DualSense Edge.

"We wanted it to be natural," Steve Cardinali, a mechanical engineer on the Controller team, told Tom's Hardware. "You're playing a game on your Steam Deck, and you go sit on your couch, you play it on Controller, it feels similar."

That, he said, kept the feature set largely down to what is on the Steam Deck, minus the addition of Grip Sense, which can detect when you're holding the controller and effectively be used as a virtual button. Cradinali said that was added for the growing number of gyro users in competitive games, who need a tool for "ratcheting," or activating, disabling, or toggling gyro for motion controls.

"That one kind of snuck in there, because we feel like that's an important feature for those kinds of games, he added. "We didn't want to overburden the product with too much additional cost or weight or battery consumption. We wanted it to be a great controller for everybody."

The one other big new feature are the TMR (Tunneling Magnetoresistance) joysticks, which help prevent drift. Griffais said that while they considered that for the Steam Deck, the technology was "nascent." Now, it's more mature.One feature from the Steam Deck is missing from the Controller — a headphone jack, which you can find on other gamepads, letting you chat with your friends from your couch and a wired headset."It's just very, very hard to productize, like in terms of the audio bandwidth and the additional cost and complexity in the system design," Griffais said." I think it's something we evaluated, and then we looked at all these other features and we focused on that instead. No, it's not to say that we don't see the value there. So it's more that it didn't make the cut this time around."

The Controller Puck: Respecting your desk

The Steam Controller comes with a small puck, which serves dual roles as a 2.4 GHz wireless connection and a docking station to charge the system. I'm very used to seeing simple USB dongles or massive USB controller docks. Valve's proprietary connection allows for up to four controllers to be connected to one dock.

According to Cardinalli, it's "a hard thing to ask" people to deal with a dongle (heard, I only have so many USB ports) or a large dock, which takes up a lot of desk space. The combination of the two minimizes the desk space while also easily charging the controller.

"And then it has the added benefit that it has this nice, satisfying little click when you put it over, it snaps into place, Cardinali said. "You don't have to, like, worry about plugging it in."

He also highlighted the community of makers who have built add-ons for the Steam Deck. He fully expects people with 3D printers to build fuller docks, and says that the smaller size doesn't prescribe what kind of designs can be thought up.

Steam Input and the learning curve

If you're expecting Valve to teach you how to use the Controller, think again. Steam will push you to update your Controller and the associated Puck, a 2.4 GHz dongle and charging dock, and advise you to use the Steam button to go into Big Picture mode. After that, you're on your own, and it mostly works like an Xbox controller. There's no game, like Aperture Desk Job, for the Steam Deck, to school you on more advanced features.

The back buttons, gyroscope, and new Grip Sense feature, which detects where you touch the controller, are all built into Steam Input. But as Cardinali pointed out, the main controller features largely work without customization.

"We wanted it to be out of the box, easy to use for people who maybe just want a controller that works like a controller and how they would expect, so that you're seeing that element there, of course," he said. "And a lot of thought went into that process."

"It's really important to us that if you don't want to deal with any of that stuff… that the surface-level experience gets you controller compatibility in games that are meant for controllers without any sort of tinkering," added Griffais. "So the steam input stuff is there if you want it, but we don't want it to be a required element to just experience the baseline functionality there."

The Steam Controller team is working on a series of tutorials on setting up some of those functions, including customizing the touchpads, setting up gyro and other input methods, to get people exposed to Steam Input and its functionality "without being too overwhelming."

Griffais did suggest that there have been conversations within Valve about adapting Aperture Desk Job to the Steam Controller in some fashion, but couldn't guarantee it would happen. The game does feature parts that teach you how to use the Steam Deck's touchscreen and microphone, beyond the otherwise similar controls.

All roads lead to Steam

The Steam Controller is designed for devices that use Steam. It works with Windowsand with Macs, but Steam has to be running. Otherwise, it's seen as a hybrid mouse/keyboard input device. (Even on a PlayStation, it's seen as a mouse. The exception is Linux, where Valve has a driver in the kernel with gamepad functionality).

That's not to say you can't play games purchased outside of Steam — you can add most titles to Steam using the "Add a Non-Steam Game to My Library" option.

But wouldn't letting the Controller work out of the box with more devices and without Steam better follow Valve's PC gaming ethos? Griffais said there are other considerations.

"We're limited in what we can do with things like core operating system drivers and such, right?" he said. "Xbox controllers have built-in support within Windows itself. PlayStation controllers have a driver that they work with Microsoft on."

He said that Valve would rather put it all in Steam, to not need a kernel driver, which could potentially add system instability."

We're really happy with not having a kernel driver, because it comes with the onus of not messing it up, right?" he said. "And so right now, the current method of supporting the controller is pretty safe."

Releasing the Steam Controller now

It seems that every time in modern history that Valve tries to release hardware, there's a global issue fighting them. The Steam Deck came out amidst the worst of the Covid-19 pandemic. The Steam Machine and Steam Frame are delayed due to the chip shortage. Though the Steam Controller is releasing separately, today's economics still affected the $99 gamepad.

"Our price reflects the reality of building the product and getting it to customers," Griffais said, adding that tariffs are a factor, depending on the region.

(The Steam Deck will cost $99 in the U.S.; $149 CAD in Canada; €99 in the European Union; £85 in the UK; $149 AUD in Australia; and 419 złoty in Poland.

But the memory shortages, which are affecting Valve's other hardware, like the existing Steam Deck OLED, don't affect the controller as much, he said, adding that "it would have been way worse during Covid" due to the microcontroller shortage at the time.

But today's economics and market dynamics didn't have an effect on the controller as it's shipping.

"I mean, those conversations happened way earlier on in development of the program, so nothing that kind of came about in the past, call it year, really affected any final feature decision, right?" Cardinali said. "Those were made way earlier."

The Steam Controller will be available to add to your Steam Cart on Monday, May 4. For more, see our Steam Controller review.
