Dark Souls 2 gets six-player seamless co-op mod in public alpha

Six players can now travel across Dark Souls 2 together without breaking apart.

Mod creator Yui has released a public alpha of a seamless co-op mod for Dark Souls 2: Scholar of the First Sin on PC, according to Eurogamer. It was the only game in the Dark Souls trilogy still without one.

In the original game, co-op is stop-start. Players leave summon signs, join another world for a boss, then return to their own game. This mod, a fan-made change to how the game works, keeps up to six players in one shared session and keeps their progress synchronised.

That means fewer blockers. The party stays together after boss fights and area changes instead of splitting up. Yui built the mod on the same idea as earlier seamless co-op mods for Dark Souls Remastered, Dark Souls 3, Elden Ring and Armored Core.

The alpha, an early test version still in active development, is listed on NexusMods as 'Seamless Co-op (Dark Souls 2)' under Dark Souls 2 mod ID 1468. The listing describes it as an overhaul of the co-operative side of Scholar of the First Sin's multiplayer, the updated edition of the game. It can be downloaded from NexusMods and GitHub, with Yui's author page linking the wider set of mods.

Yui had earlier pointed to mid-September as a provisional window before confirming 22 September 2026 as the release date in a Patreon announcement. The public alpha followed on that schedule, with fixes arriving quickly after launch.

Expect bugs. Enemies can fall out of sync when someone dies, including the boss fights against Velstadt and Sinh. Opening or closing doors and picking up items may also fail to register for everyone in the group.

Fixes are already landing. Multiple patches were out at the time of reporting, including a fix for a major performance glitch affecting players on Intel systems, as reported by PC Gamer. PC Gamer noted the mod arrives 12 years after Dark Souls 2 first launched, finally allowing uninterrupted co-op.

For fans, this means a slower, shared trip through Drangleic. One party can stick together for the whole run rather than meeting briefly at each fog gate. It is a different way to learn the maps, share the risks and keep the same group together to the end.
