About this project

ASI mod (Ultimate ASI Loader) for Steam build 1.0.0.2976 / game version 2.03.02 only; turns itself off on other builds. Each player stays in their own save and sees the other; hostile enemies near the host are shared (experimental); quests, NPCs and items are not shared; Steam friends only. GPL-3.0. The author stopped work at v0.2.0 and invites others to continue it. A revival focused on shared quest progress is claimed in cranebeaker/coop-anything#51: builds on Linux with clang-cl + xwin, one-PC echo smoke test ran under Proton (no automated two-player test yet). Research and dated notes in games/crimson-desert.
