Hype around mobile gaming controllers is not going away any time soon. More people are gaming on mobile, and controllers that make it possible are in demand. GameSir very well understands the needs of gamers who play on multiple devices and platforms, and they’ve brought a transforming controller to CES 2026 in collaboration with Hyperkin, which will have you sold for good.
The X5 Alteron controller gets the best of both worlds: GameSir’s ergonomic engineering that makes it the first choice for gamers, and Hyperkin’s knack for designing retro controllers. What sets the modular controller apart is the swappable module system that allows gamers to completely change the layout from symmetrical to asymmetrical thumbsticks, to changing the D-pad and face buttons.
Designer: GameSir and Hyperkin
This level of customization gives mobile gamers the option to carry just one controller, whether playing on Switch, Android, PC, iPhone, or iPad. The ability to swap and replace buttons, or add the mouse-level precision trackpad (yes, this controller can do that), gives you tactical advantage in all genres of games like racing, strategy, RPGs, and, in particular, FPS titles. GameSir already impressed at CES with the Swift Drive controller, and the X5 Alteron is even better. The gamepad is a literal transformer of the gaming controllers world, as it changes shape, style, and size depending on what device you are playing it with.
Want the Xbox-style layout, or the feel of the N64 controller setup? The modular controller makes quick work of that. It even has a module dedicated to fighting titles for maximum precision. The possibilities are endless as the controller sets a new yardstick for customizable gaming hardware. Of course, it has all the essentials of a gaming controller intact while doing this. There are Hall effect triggers and capacitive sticks for zero stick drift, mouse click, rumble motors, and hot swappable ABXY buttons. Transformable D-Pad and much more. Alteron can be extended to 213mm to fit all devices you throw at it.
The gaming accessory charges via USB-C port, and the connectivity with the devices is made via Bluetooth 5.2. Latency should not be a worry as GameSir and Hyperkin optimize their accessories very nicely. The GameSir x Hyperkin X5 Alteron controller will be released in the coming months, but there is no detail about pricing yet. Given how GameSir controllers are tactically priced, this one should be right there in the sweet zone. Could it replace all your controllers going forward for a one-stop solution? It pretty well can be the prime contender!
