Quick Scoop

You get the MX-18 in TTK Testing by unlocking or selecting it from the game’s weapon/loadout system once it’s available to your account or the current test build. Community sources show TTK Testing’s loadout menu lets players swap weapons in-game, and the experience is still mid-update, so weapon availability can shift quickly.

What To Try

  • Open the loadout menu in-game and check the primary weapon list first. The game’s recent showcase shows weapons are changed from the loadout screen, and some guns can appear locked until the right progression or update state is met.
  • Look for the weapon in the Roblox experience page title or update notes. The current listing explicitly shows TTK Testing [M18] , which suggests the build is centered on M18-related content, while the wiki’s update page also tracks M18-related changes.
  • If you do not see MX-18 specifically, it may be a naming mix-up with M18 or MK18. One recent video shows MK18 in the loadout and notes that it was locked, which fits the kind of early-access weapon gating TTK Testing currently uses.

Why It May Be Missing

TTK Testing is still in an early-access, fast-changing state, and its own game description says content may be missing or temporarily broken during updates. That means a weapon like MX-18 may not be universally obtainable yet, may be locked behind an update, or may simply be listed under a slightly different name in the current build.

Best Check Order

  1. Join the latest live build of TTK Testing.
  2. Open the loadout menu and inspect primaries.
  3. Check whether the weapon is locked, renamed, or temporarily removed.
  4. Compare with the latest wiki/update page and recent gameplay clips for the current naming.

If you want the answer in a cleaner forum-style format, the safest wording is: the MX-18 is likely obtained through the current loadout/unlock system, but in the June 2026 build it may be unavailable, renamed, or locked depending on patch state.
