I’m not fully sure which game you mean by “thanos,” but if you mean Thanos Simulator / Infinity Gauntlet Thanos Simulator , the Demon Sword seems to be a hidden or special weapon similar to the other secret swords people mention in that game’s community. Public results I found point more toward related secret weapons like Twilight Sword , Stormbreaker , and a wiki weapons list, but not a clear, confirmed Demon Sword guide for that exact title.

What I found

  • A Thanos Simulator weapons page exists, which suggests the game has a structured secret-weapon system.
  • Videos and posts around the game focus on unlocking special swords such as Twilight Sword and other secret weapons, usually through fragments, forge interaction, or specific requirements.
  • I did not find a reliable source that explicitly confirms the exact steps for a “Demon Sword” in Thanos Simulator.

Best guess

If the Demon Sword is part of the same weapon progression, the unlock pattern is likely one of these:

  1. Collect a set number of fragments or kills.
  2. Reach the forge or special crafting area.
  3. Hold or equip a required item first, then interact with the forge.
  4. Claim the weapon only after the game triggers the unlock condition.

That matches how other secret weapons in the game are described by players.

Most likely issue

The name may be slightly off. Players often mix up names like:

  • Demon Sword
  • Twilight Sword
  • Thanos Sword
  • secret weapon variants

So the fastest way to get the right answer is to verify the exact game title or the weapon’s in-game name, because the steps can differ a lot between Roblox games with similar names.

Current status

At the moment, the most accurate answer is: I can’t confirm a trusted Demon Sword walkthrough for Thanos from the public results I found, but the game’s other secret weapons appear to use fragment-based unlocking and forge interaction.
