GameSir and Hyperkin reveal powerful X5 Alteron modular mobile controller
GameSir and Hyperkin have teamed up to launch something truly new for mobile and retro gamers. The X5 Alteron is being called the world’s first fully modular mobile gaming controller, and it brings a fresh idea to how a controller can look, feel, and work.
This controller is made for players who enjoy both old-school games and modern titles. It mixes Hyperkin’s love for retro design with GameSir’s focus on comfort and smart engineering. The result is a controller that can change its shape, button layout, and even its size, depending on how and what you want to play.
The X5 Alteron uses a telescopic arm that can expand up to 213 mm. This allows it to fit different phones and tablets with ease. It supports iPhone, iPad, Android devices, Nintendo Switch 1 and 2, and even PC through Bluetooth. Switching between devices is smooth, so you can move from one platform to another without trouble.
In terms of design, the controller blends retro colours and styles with a clean, modern look. Each module feels carefully made, with both looks and comfort in mind. The modular system lets players fully customise their setup. You can change thumbstick layouts, swap face buttons, adjust the D-Pad, and even replace entire control modules.
For retro fans, there are special modules inspired by classic controllers. There is a GameCube-style module for Nintendo Switch Online games, an N64-style module for classic fans, and a Fight Pad module for fighting games. There is also a Track Pad module, which is useful for FPS games or mouse-like control.
Performance is clearly a big focus. The X5 Alteron uses capacitive thumbsticks that help remove stick drift. Stick height can be changed to match your hand size or play style. The triggers use Hall Effect technology with mouse-click style feedback, making them fast and reliable. Rumble motors add vibration for better immersion, while back buttons give extra control during gameplay.
X5 Alteron hot-swappable ABXY buttons
The controller also supports hot-swappable ABXY buttons, different D-Pad styles, and both tactile and membrane buttons, so every press feels natural. Bluetooth 5.2 ensures a stable connection, and USB Type-C charging keeps things simple and fast.
With its deep customisation, wide device support, and mix of retro and modern ideas, the X5 Alteron aims to be one controller that can handle almost any game. GameSir and Hyperkin are clearly setting a new direction for mobile and modular gaming controllers.
