A fan-led team has successfully resurrected Sony's defunct hero shooter Concord by creating reverse-engineered custom servers. However, it appears that the project may be taken down in the near future at the company’s request.

The details:

Sony’s Concord, originally launched in August 2024, was pulled offline just two weeks later after selling fewer than 25,000 copies, with Sony issuing refunds to all players and shutting down its developer, Firewalk Studios. In an attempt to bring the short-lived title back from the dead, a team of volunteer developers spent months reverse engineering the game’s backend systems, eventually making it playable via custom servers.
As shown in YouTube videos, the team was able to play full matches of the Clash Point game mode with matchmaking functionality. The project, called Concord Delta, was then opened up to playtesters in all regions, with the developers stating that "it's playable, but buggy."
However, shortly after the team shared YouTube videos demonstrating the working custom servers, MarkScan, a digital asset protection firm that handles copyright enforcement for Sony, issued DMCA takedowns removing the gameplay footage from YouTube. While the team has not received a direct takedown against the custom server project itself, it announced on their Discord server (via The Game Post) that they would "pause invites for the time being" in response to the "worrying legal action."
The Concord Delta developers also emphasized that the playtest was only open to players who legitimately owned the game, attempting to keep the project "as legal as we realistically can.” It added that it would go through the Discord server to remove any links offering the game’s files.
