GameSir and Hyperkin have announced the X5 Alteron, a new modular gaming controller, at CES 2026. The device, described by its creators as the world's first fully modular mobile controller, is designed for broad compatibility with various gaming platforms and mobile devices, emphasizing customizable control layouts.
Overview and Design
The X5 Alteron is a collaborative project between accessory manufacturers GameSir and Hyperkin. It features a clamp-on style design with an extendable telescopic arm, enabling it to securely attach to and accommodate smartphones, tablets, and Nintendo Switch models. Bluetooth connectivity also allows for its use as a standalone controller with PCs and other consoles. The controller is planned to be available in gray and black color options.
Modular Customization
A key feature of the X5 Alteron is its modular design, which allows users to interchange most front-facing controls, including sticks, D-pads, and buttons. These modules attach magnetically, though an early prototype demonstration noted their removal as challenging. The system supports hot-swappable buttons and adjustable stick heights.
Anticipated customization options and modules include:
- Thumbsticks: Configurations for symmetrical or asymmetrical placement, with adjustable height.
- Action Buttons: Adjustable location, quantity, and layout.
- D-pad: Customization of its appearance and tactile feel.
- Retro Modules: Modules designed to emulate Nintendo 64 and GameCube controllers, intended for use with older titles, such as those on Nintendo Switch Online.
- Trackpad Module: A module incorporating a trackpad to replicate mouse functionality, designed for games like first-person shooters.
- Other Configurations: A six-button array and a fight pad design.
Technical Specifications and Features
The X5 Alteron incorporates several modern functionalities:
- Capacitive Sticks: These are utilized for enhanced precision.
- Hall-Effect Analog Triggers: Located on the rear, these triggers offer an adjustable shorter travel distance and can feature selectable operating modes, including tactile micro-switch or Hall Effect analog functionality.
- Rumble Motors: Included to provide force feedback effects.
- Charging: The device requires charging via USB-C.
The controller's design integrates functionality similar to GameSir’s 2024 G8 Plus model, known for its expanding telescopic mechanism.
Compatibility
The controller is designed for wide compatibility, supporting:
- iPhones
- Android smartphones
- Nintendo Switch series
- The forthcoming Nintendo Switch 2
- iPads
- PCs (via Bluetooth)
Development Status
At its announcement during CES 2026, the X5 Alteron was showcased as a non-functional prototype. Specific release dates, pricing information, and details regarding the sale of alternate control modules have not yet been disclosed by GameSir or Hyperkin.
