GameSir and Hyperkin have announced a new collaboration that brings a different approach to mobile and multi-platform gaming controllers. The two companies introduced the X5 Alteron, a fully modular mobile gaming controller designed to adapt to a wide range of gaming styles, platforms, and genres. According to the announcement, the controller is aimed at players who want a single device that can be customized both in layout and physical design.
The X5 Alteron is built around a modular system that allows users to change how the controller looks and feels. GameSir’s telescopic arm design enables the controller to expand and contract, allowing it to fit various devices while also changing its overall size. This makes it suitable for smartphones, tablets, and handheld-style setups. The controller supports wireless connectivity across iPhone, iPad, Android devices, and Nintendo Switch systems, with additional Bluetooth support for PC gaming.
Cross-platform use is handled through GameSir’s wireless switching technology, which allows players to move between supported devices without lengthy reconnection steps. The controller uses Bluetooth 5.2, offering stable connections and compatibility with multiple platforms. Charging is handled through a USB Type-C port, aligning with current hardware standards.


From a design perspective, the X5 Alteron combines Hyperkin’s retro-inspired visual style with modern controller hardware. The modular components are available in designs that reference classic gaming hardware while maintaining compatibility with current games. This approach is intended to appeal to players who enjoy retro titles as well as those focused on modern releases.
The X5 Alteron places a strong emphasis on flexibility in its control layout. Users can rearrange the thumbsticks between symmetrical, offset, or top-stick positions, allowing the controller to adapt to different play styles and genres. The D-pad is also adjustable, giving players the option to fine-tune directional input based on personal preference.

Face button configuration is equally adaptable. The controller supports different layout standards, making it suitable for use across multiple platforms. Its hot-swappable ABXY buttons let users switch between an X Input-style arrangement and a Nintendo Switch-style layout, ensuring consistent muscle memory whether gaming on PC, console, or handheld systems.
Hyperkin and GameSir have also introduced a range of optional modules for the controller. These include a Fight Pad module designed for fighting games, offering a layout focused on directional and button precision. There are also GameCube-style and N64-style modules aimed at players using emulation software or Nintendo Switch Online. These modules are designed to recreate the feel and button placement of classic controllers while remaining compatible with modern systems.
For players focused on shooters or mouse-like input, the X5 Alteron offers a Track Pad module. This module is intended for FPS titles or situations where pointer-style control is preferred. Additional options include adjustable thumbstick heights, allowing players to fine-tune control based on comfort and game requirements.



In terms of internal components, the controller uses capacitive thumbsticks, which are designed to reduce wear over time. Hall Effect analog triggers are also included, offering consistent input and reduced mechanical degradation compared to traditional trigger designs. The controller features rumble motors for in-game feedback and back buttons that can be assigned to additional functions.
The X5 Alteron also supports both tactile and membrane button types, giving users control over how button presses feel during gameplay. This flexibility allows the controller to be adjusted for different genres, from action games to platformers and competitive titles.
With the X5 Alteron, GameSir and Hyperkin are positioning the controller as a single solution for players who use multiple platforms and enjoy different gaming styles. By focusing on modular hardware, broad device compatibility, and retro-inspired options, the controller is designed to reduce the need for multiple specialized controllers.
Details regarding pricing, release dates, and regional availability have not yet been shared. Both companies have indicated that additional information will be released closer to launch.
