TRX

About

The original Tomb Raider trilogy (1996-1998) are action-adventure games developed by Core Design and published by Eidos Interactive, following archaeologist Lara Croft through puzzle- and combat-filled levels across three separate games — Tomb Raider, Tomb Raider II, and Tomb Raider III. TRX is an open-source, single-engine reimplementation of Tomb Raider I, II, and III (plus custom levels), built through decompilation and open-source replacements for proprietary components while respecting each original engine's distinct mechanics. It runs on Windows, Linux, and macOS, requires the player's own legally obtained original game disc images, and is under active development, with all three games reportedly fully playable start to finish and Tomb Raider IV support underway.

How it differs from the original

The project adds enhancements not in the originals: restored content like Tomb Raider 1's originally-cut braid on Lara's model, an enemy health bar and adjustable UI scaling, a photo mode, 3D pickups, skybox support, an updated moveset including sprinting, customizable draw distance, a developer console, detailed level statistics, and expanded controller support with multi-key combo bindings; HD texture packs are explicitly not planned.

Getting started

Download the latest release and follow the included installation instructions; the player must supply their own legally obtained Tomb Raider I-III disc images, since the project doesn't include original game assets. Controls fully support keyboards and a wide range of gamepads out of the box, with customizable bindings including multi-key combos.

Roadmap

Support for Tomb Raider IV is under active development, though the README says tickets for TR4-specific issues raised before it's fully supported will likely be closed.
