StarLancer (OpenReliant)

WIN

OpenReliant: an open-source, faithful engine reimplementation of StarLancer, the space combat simulator by Warthog and Digital Anvil that Microsoft published in 2000. It is written in Zig on SDL3 and renders with Vulkan (Metal on macOS) through SDL’s GPU API, on Linux, macOS, and Windows, using the data from your own copy. The whole campaign is playable from the first mission to the end, and the original’s saved games carry on. It has all ships with the original flight model, weapons, damage, AI, and cockpit displays, eight camera views with 3D cockpits, full missions and scripts, per-pixel shading, real-time shadows, 3D positional audio, controllers and flight sticks with rumble, and an --original switch that restores the original graphics and sound. It supports mods with Luau scripts, which add ships, weapons, pilots, game modes, and campaigns. It is in beta; version 0.20.0 came out on October 22.

You needThe files from your own retail copy of StarLancer (the repository contains no textures, models, sound effects, music, videos, or game binaries). Plus Windows (x86-64 or ARM64), Linux (x86-64 or ARM64), or macOS (Intel or Apple Silicon); on macOS you need to remove the quarantine flag because the builds aren’t signed.
