A sequel to MySims Agents called MySims Agents 2 was planned, but was ultimately shelved in Fall 2009. Years later on May 12, 2023, designer Brian Kaiser shared an old completed story outline for the game on his Twitter account. Based on the outline, the plot would have revolved around the player investigating a series of strange events involving an unknown energy source (later revealed to be seeping through portals from the Nightmare Realm), all while contending with the new S.P.A. director Morgan (a reworked version of the scrapped character Vice Admiral Morgan from MySims Kingdom) and her advisors Dragomir and Svetlana (reused from MySims SkyHeroes), who has shut down several branches of the agency as part of "restructuring" and captured Walker after he began to investigate them. Several characters from the original game would have returned, with Roxie Road, Jenny, Dr. F, Buddy, and Vic Vector all being part of the player's team as they solve cases all over the globe. While full gameplay details are unknown (aside from a new grapple hook mechanic), some pieces of concept art have been released since, such as designs for Morgan's various monster forms.
