Itâs been over a year since Sony pulled the plug on Firewalkâs Concord, which reportedly cost more than $200 million to develop. After sparse player engagement, the project shut down on September 6, 2024. However, a small team of modders has since revived Concord.
Reported by The Game Post, a team of modders, including developers Red, open_wizard, and gwog, formed a grassroots project called Concord Delta. The team spent months reverse-engineering the backend API to create custom PC servers, allowing matchmaking and matches, despite bugs. The project launched on November 14, and the team published YouTube videos showcasing test footage.
However, Concordâs comeback was short-lived, as Sonyâs copyright-enforcement partner, MarkScan, a digital asset protection firm, sent a DMCA takedown notice to YouTube for videos featuring Concord Deltaâs gameplay.
In response, one of the lead modders, Red, took Concord Deltaâs Discord server and announced, âDue to worrying legal action, weâve decided to pause invites for the time being.â Players whoâve already gained access can play on Concord Deltaâs servers. For the time being, Sony hasnât sent a direct cease-and-desist to the Concord Delta modding team.
Earlier on, Red warned the community about legal problems and stated:
The project is still WIP. Itâs playable, but buggy. I know this sucks for people who got forcefully refunded, but lawyers are most likely already watching everything we do, and I want to ensure this project stays as legal as we realistically can. We will be removing any posts containing links to copyrighted files.
Many online gamers argue that Sony is trying to hinder efforts to preserve Concord, despite having shut down official servers long ago. Others claim Sony is trying to bury Concordâs memory and take it back to the grave. Concord was also mentioned in the UK Parliament, where it was cited as an example of games being shut down without a clear lifespan at the point of sale.
For now, game servers remain operational for invite-holders via the Discord channel. However, Concord Deltaâs future remains dim without Sonyâs approval. The question remains how far Sony will go in shuttering the fan project aimed at reviving the short-lived live-service shooter. Sony’s repeated attempts to capture the games-as-a-service market, which has seen significant investments since its success with Helldivers 2 on multiple platforms.
