The Mechanical Gauntlet in Roblox is usually obtained in Thanos Simulator / Infinity Gauntlet by defeating the correct boss tied to the update, then claiming the badge or reward that unlocks it.

What players are saying

  • One guide says you need to reach the boss area, use the required gear, survive the shield phase, and then finish the boss when the shield drops.
  • Another source says the Mechanical Gloves/Mechanical Gauntlet come from beating the Doom boss.
  • A wiki page for the game lists multiple weapon unlocks, including special gauntlet-type weapons, which fits that style of progression.

Simple steps

  1. Open the game and get the strongest gear you already have.
  2. Progress to the boss linked to the Mechanical Gauntlet unlock.
  3. Wait for the boss’s shield or protection phase to end.
  4. Deal damage fast during the opening.
  5. Claim the badge or reward after the win.

Helpful tip

If the boss has a shield, players recommend using mobility or healing tools while waiting, then switching to your highest-damage weapon when the shield disappears.

Note

The exact unlock method can change with updates, so the boss name or requirement may differ slightly depending on the current version of the game.
