Initial Release: March 1998
Platforms: Originally Windows and Macintosh only. Also included in the TR1 iOS and Android apps. Included in Tomb Raider I-III Remastered for PlayStation 4 and 5, Xbox One, Xbox Series X|S, Nintendo Switch, and PC via Steam, GOG, and Epic Games.
Spoiler-free Synopsis: These bonus levels comprise two mini-adventures designed to challenge both novice and expert raiders. In the first two levels, "Shadow of the Cat," Lara returns to the city of Khamoon in search of an undiscovered tomb dedicated to the Egyptian cat-goddess, Bastet. In "Unfinished Business," having learned of the existence of a hive of surviving creatures guarding an alien hatchery, Lara returns to Atlantis to destroy the mutants before they invade again.
Saving Your Game: Unlimited saves at any point. Savegame files are available in case you make a bad save, want to skip a level without missing any pick-ups, etc.
Secrets: As in the original game, the number of secrets in each level varies. They consist of ammunition, medipaks, and the occasional weapon. A chime sounds when you locate a secret, and the statistics screen at the end of each level tells how many secrets were available in that level, along with how many you found. There is no bonus for finding all secrets. And, as always, my walkthrough includes the location of all secrets.
Classic Tomb Raider Games on New Systems: Tomb Raider 1-3 Remastered (link to blog post) is the best way to play Unfinished Business on modern computers and consoles, but if you need help with a legacy version, check out my classic TR1 Downloads page.
Becoming an Expert Raider
Controls are the same as in Tomb Raider. If you need a refresher, check out my TR1 Controls and Gameplay Tips & Strategy pages. They include pointers on moving Lara through her environment, conserving health and ammo, using the menu and inventory systems, and much more.
Tomb Raider: Unfinished Business
In Tomb Raider I-III Remastered, the Unfinished Business levels come before the Shadow of the Cat levels, as the developers originally intended. I'll update the walkthrough soon, but for now, just choose Level 3: Atlantean Stronghold first.
