SurrealEngine: Open-source reimplementation of Unreal Engine with playable UT99

Original Article ↗ Hacker News Discussion ↗

An open-source reimplementation of the original Unreal Engine has sparked excitement among classic PC shooter fans, who see it as a way to keep games like Unreal Tournament ’99 and Deus Ex playable with modern quality-of-life improvements. Commenters contrast this community-led preservation work with Epic Games’ reluctance to open-source older Unreal Engine versions or maintain the Unreal Tournament franchise, especially compared to id Software’s GPL releases. The project is also discussed in the broader context of retro engine ports, licensing quirks, and the decline of fast-paced “arena” shooters in favor of newer multiplayer formats.

Nostalgia and Community Preservation

  • Many recall UT99, Deus Ex, and UT2004 as peak FPS experiences, praising their atmosphere, music, and user-made maps.
  • Players reminisce about specific modes (Bunny Tracks, Instagib, Onslaught/ONS-Torlan), LAN parties, and strong bot AI that made small gatherings fun.
  • There’s broad appreciation for projects that keep classic games playable and accessible on modern systems.

SurrealEngine and Related UE1 Projects

  • SurrealEngine is seen as an ambitious, standalone reimplementation of Unreal Engine 1, with the goal of faithfully running games like UT99 and Deus Ex.
  • A separate project, Surreal98 (formerly DXU24), aims to run UE1 games inside UE5 with modern features like VR; that one appears commercial and closed.
  • Some worry about reimplementations that depend on heavy modern engines versus lean, SDL/OpenGL-style ports that can run on low-end or niche platforms.

Licensing and Third-Party Code

  • A side thread debates a “cutesy” license in a third-party audio library (DUMB), with criticism that joke-style licenses create legal ambiguity.
  • Others note DUMB is effectively BSD-like and argue that people should choose what makes them happy, while opponents stress licenses are legal tools, not entertainment.

Epic, Open Sourcing, and Old Catalog

  • Many wish Epic would open-source Unreal Engine 1 (as id did with older idTech) or at least release code for its classic DOS games.
  • An old statement from Epic indicated UE1 open-sourcing might be possible but would require cleanup; commenters note this still hasn’t happened and suspect Fortnite’s success shifted priorities.
  • Some argue Epic could just strip proprietary dependencies and let the community patch; others point out Epic already gives limited source access to trusted community projects.

Arena FPS Genre and Modern Alternatives

  • Several note that classic arena FPS (Quake/UT style) is effectively a dead or niche genre, supplanted by tactical shooters, hero shooters, and battle royale games.
  • A few modern or open-source alternatives are mentioned (e.g., Quake Champions, Xonotic, Titanfall 2, Splatoon 3), but none match the old player counts or “feel” for many.
  • There’s skepticism a new Unreal Tournament could justify its cost, despite nostalgia-driven demand.
