In 1999, Tomb Raider II was re-released for PC as Tomb Raider II Gold in North America and Tomb Raider II: Golden Mask elsewhere. The game comprises the scenarios of the original Tomb Raider II and four new bonus levels in a separate mini-adventure entitled "The Golden Mask". Unlike the other two Gold games, however, The Golden Mask contains no story ties to its corresponding game from the main Tomb Raider series.

The story involves Lara Croft coming across some clues referring to a small island in the Bering Sea: a faded photograph showing an Inuit whale hunter holding what looks like an ancient golden mask, an old newspaper from 1945 referring to a conflict over an Alaskan gold discovery, and a secret kind of fortified military mine base. Lara is primarily interested in finding the mask, as it is rumoured to be the famed Golden Mask of Tornarsuk, a greater spirit said to bestow powers of resurrection on the mask wearer.
