Description
Dark Souls III Seamless Co-op is Yui's DS3 campaign session, not Scholar DS2, not Remastered DS1, and not Elden Ring. Build 0.1.1 targets 1.15.2. Fog walls and their teleports are gone.
## One rest resets the world for everyone When anyone sits at a bonfire, the world resets for the party. Co-op items show up after that rest. Sit together before a boss so flags match. Keep vanilla .sl2 aside — Seamless saves do not belong on official DS3.
## ds3sc_launcher and the EAC splash Password lives next to ds3sc_launcher.exe. EAC splash means the launcher was skipped. Mixed DLC (Ashes / Ringed City) is the usual join fail, not a password typo. Same author as Elden Ring Seamless, different Game folder and ds3sc_ prefix.
Cemetery of Ash to the last lord together
- Up to 6 players in the open world (host + 5).
- No fog walls — the multiplayer zone is the whole map.
- Boss kills and area clears do not end the session.
- NPC dialogue and talk events stay in sync.
- Bonfire rest resets the world for everyone.
- Progress in the host world carries when guests go home.
- Launch
ds3sc_launcher.exe, not the Steam exe. - Steam online, same password in
ds3sc_settings.ini. Yui-style overhaul for game 1.15.2: one session from Cemetery of Ash to the last lord. Deaths respawn at the last bonfire; bosses no longer send guests home.
