OpenGothic

Open source remake of Gothic 2: Night of the Raven.

Motivation: The original Gothic 1 and Gothic 2 are still great games, but it's not easy to make them work on modern systems. The goal of this project is to make a feature complete Gothic game client compatible with the original game data and mods.

Work in progress

The original game has been replicated fully; you can complete both the main quest and the addon. Check out the bugtracker for a list of known issues.

Mods compatibility

• Content mods (retexture/reworld/animations)
• Mods bases on Ikarus/LeGo
• AST sdk
• Mods bases on Union (not possible)
• DirectX11 - same as Union, but don't worry - OpenGothic has nice graphics out of the box
