Closed playtest listing fuels speculation that NetherRealm’s Injustice 3 may be underway

A Good Gamer Group listing shows a closed playtest for an unannounced AAA 2D fighting game was scheduled in the United States between September 14 and September 15, 2026, a listing that fans have connected to NetherRealm Studios and the rumored Injustice 3.
NetherRealm Studios has remained quiet since the end of content support for Mortal Kombat 1, and reports in April 2026 first suggested a new Injustice title was in development. A social-media post accompanying recent coverage stated, 'INJUSTICE 3' is seemingly having playtests in California currently, feeding further speculation about the franchise's next entry.
The Good Gamer Group advertisement named only an unreleased AAA 2D fighting game and specified the U.S. as the location for a closed playtest on September 14–15; it did not provide the project's title. Observers have nonetheless linked the listing to NetherRealm because the studio is one of the developers most associated with large-scale 2D fighting games.
April 2026 reports that Injustice 3 was in development are separate from the Good Gamer Group listing, but the two items have been cited together by fans as corroborating signs. The recent playtest notice has been interpreted by some commentators as an indicator that internal development could have progressed to a stage warranting player testing.
NetherRealm Studios has not issued any official announcement confirming Injustice 3 or the reported playtest, and the Good Gamer Group posting stopped short of naming the game it was recruiting for. Multiple outlets and social posts referenced in recent coverage have therefore treated the connection between the listing and Injustice 3 as speculative rather than confirmed.
Fans point to major industry showcases as potential reveal platforms should NetherRealm choose to announce the title publicly; coverage has noted The Game Awards 2026 as the remaining large event in the year where a studio reveal might occur. Past coverage cited in the reporting mentions that NetherRealm has announced titles at high-profile events before, which informs expectations among the community.
With no official confirmation from NetherRealm, the immediate factual development remains the Good Gamer Group listing for a closed U.S. playtest on September 14–15, 2026; observers and fans are watching for any formal announcement or a reveal at The Game Awards 2026.
