Around 2004, prior to the release of "Half-Life 2", Fearon had been planning to release "Sven Co-op" on Steam, but this did not work out due to confusion between the "Sven Co-op" team and Valve. Further, Fearon and the team had started work on a "Sven Co-op 2" in anticipation of using the Source engine from "Half-Life 2". Though they had developed a large number of assets for the mod, they were hampered by the lack of the SDK, which had been pushed back along with the release of "Half-Life 2". Many of the team members had started to move on to other projects, and Fearon found they lost too many key members to continue development. Around this point Fearon opted to leave the project, giving the project lead over to Josh Polito.
