Arcanum: Of Steamworks and Magick Obscura — Native 64-Bit Port
Native 64-Bit SDL2 Port (In Active Development)
Arcanum: Of Steamworks and Magick Obscura (Troika Games, 2001) blends Victorian industrial steampunk with high fantasy in an open-ended isometric CRPG. Our project ports the original 32-bit engine (Arcanum.exe + tig.dll Temple Interface Graphics library) to native 64-bit C++20 & SDL2 for macOS ARM64, Linux x86_64, and Linux ARM64, with 1–4 player party co-op.

Full Campaign Co-op (Beyond Vormantown)
In the original 2001 release, multiplayer was restricted to the standalone Vormantown module without world-map travel or main-story quests. Our native port brings 1–4 player co-op to the full Arcanum story campaign:
- Shared World Map & Train/Ship Travel: Party travel across Tarant, Shrouded Hills, Ashbury, Caladon, and the Vendigroth Wastes synchronizes seamlessly across all connected players.
- Synchronized Turn-Based & Real-Time Combat: When any party member enters combat, nearby co-op companions join the initiative queue automatically.
- Gamepad & Handheld UI: Radial spell/tech wheel and controller cursor snapping for Linux, ARM64 & Handhelds and Khadas VIM1S.
