You can now play a soulslike title cooperatively.
Recently, EmberWave released a multiplayer mod for Lies of P on Nexus Mods. The game was originally created as a single-player experience and did not include online functionality:
After more than a year of reverse engineering and system development, this project has been created to let players team up — explore the world, fight together, and progress through the story side by side.
The developer emphasized that the ultimate aim of the creators behind “Lies of P Coop” is to deliver a truly seamless cooperative experience.
The project is currently in alpha testing; at the moment the only completed mode is the cooperative Boss Rush, and development on a full cooperative campaign is already underway.
