Overview

  • Revealed at CES 2026, the X5 Alteron was shown as a non-working unit demonstrating its magnetic, hot-swappable front modules.
  • The companies plan modules that mimic GameCube and N64 layouts alongside options like a six-button fight pad and a trackpad for shooters.
  • An extendable telescopic mount clamps onto iPhone and Android phones, iPads, and the Nintendo Switch and Switch 2, with Bluetooth for PC use.
  • Listed features include capacitive analog sticks, Hall-Effect analog triggers, adjustable stick heights, hot-swappable buttons, and built-in rumble motors.
  • Hands-on reporting noted early usability issues such as modules being difficult to remove, and neither pricing nor a launch timeline has been announced.
