Lara Croft seeks Mjolnir, the hammer of the Norse god Thor, in Tomb Raider: Underworld.
The game builds its central mythology around Norse artifacts and legends. Lara follows clues connected to Thor’s equipment, including his belt and gauntlets, before the story leads toward Mjolnir. The hammer is presented as an ancient object of enormous power and becomes central to the game’s final stages.
Mjolnir is the modern English transliteration most commonly used for Thor’s hammer, although spellings vary in different sources. It should not be confused with Gungnir, Odin’s spear, or Gram, a sword from Germanic and Norse heroic tradition. Underworld’s use of these myths is fictionalized for the Tomb Raider narrative rather than a literal retelling of the surviving mythological texts.
