2009, and in Europe in August 2010. An attempt was made by Realtech VR to remaster the first three Tomb Raider titles for Windows, but due to not having asked permission from then-franchise owner Square Enix first, the project was cancelled. In 1997, four new levels were released in an expansion pack for the Windows version, known under the title Tomb Raider: Unfinished Business.

This version was released on Android devices in April 2015. Nude Raider An infamous part of Tomb Raiders history is a fan-made software patch dubbed Nude Raider. The patch, when added to an existing PC copy of a Tomb Raider game, caused Lara to appear naked.
