I couldn’t verify a reliable, current method for getting the MX-18 in TTK Roblox from the information I have here, and the public results I found only confirm that TTK Testing has recent updates and M18-related references, not a clear unlock guide for MX-18.

What I could confirm

  • Recent TTK Testing content mentions an M18 context and a June 2026 update cycle, but not a step-by-step MX-18 unlock path.
  • A recent tutorial about TTK Testing covers controls and settings, which suggests the game’s weapon systems and menus may change with updates.
  • I did not find a trustworthy source in the available results that clearly says how to obtain the MX-18 specifically.

Best practical check

  • Look inside the game’s current weapon shop, loadout menu, or update notes.
  • If MX-18 is tied to progression, check for rank, level, or currency requirements in the armory.
  • If it is event-locked or newly added, the unlock may only be documented in the newest patch notes or official community posts.

What this means

At the moment, the safest answer is that the MX-18 method is not clearly documented in the sources I found, so I can’t honestly give you a confirmed unlock route.
