What games can I play with Project Britannia?

Updated

You can play two full games built on the Project Britannia engine: Ultima V: Lazarus and The Ultima 6 Project. Both are fan-made recreations of the classic Origin Systems Ultima titles, running on the Dungeon Siege engine so they work on modern hardware with enhanced gameplay and graphics. The Project Britannia site hosts download links for both games, along with the engine itself and the tools needed to build your own mods.

The two playable games

Project Britannia is the shared engine and asset base behind two separate, complete games developed by different teams working together:

Game Built by What it is
Ultima V: Lazarus Team Lazarus A remake of Ultima V using the Project Britannia engine
The Ultima 6 Project Team Archon A remake of Ultima VI using the same engine

According to the site, these were "built by Team Lazarus and Team Archon collaboratively." Both take the world of Britannia from Origin Systems' Ultima series and implement it in Gas Powered Games' Dungeon Siege engine.

What "running on Project Britannia" means for you

The practical benefit is hardware and quality-of-life: you can play Ultima V and Ultima VI on modern hardware with enhanced gameplay and graphics, rather than fighting with the original releases. The engine is the same Dungeon Siege engine, extended with a custom scripting API called Skrit used to customize behavior.

What else the site gives you

Beyond the two games, the site is set up as a resource hub for the modding community:

  • Download links to both games (Ultima V: Lazarus and The Ultima 6 Project)
  • The game engine itself, which you can install in your own development environment for use with the Siege Editor
  • The Siege Tools development toolset for creating your own mods
  • A wiki recording the Project Britannia featureset plus historical details
  • Documentation for the custom "Skrit" API used to customize the Dungeon Siege engine
  • A forum where you can connect with other modders, post about your experiences with either game, and get help

Getting help and staying current

The forum is the main place to go for troubleshooting and community support. The site also notes that new mods are still being written, with links to them posted in the forum. One caveat worth knowing: the development blog is described as mostly filled with links that no longer work and announcements that no longer matter — it stands as a timeline of the project rather than a live resource, so don't rely on it for working downloads.

If you're looking for a quick-start guide to setting up Dungeon Siege for either mod, or an FAQ for installation problems, the site's author mentions these as possible future additions rather than existing pages — so for now, the forum is your best bet for installation help.
