An overlooked 2018 indie multiplayer fighter has found an unexpected second life on PC. Released on Steam by developer RetroSpecter as a free, first project, Crashphalt recently surged past 500 Steam reviews—a massive jump for a title that previously sat in single and double-digit concurrent player counts.
The Undertale Connection
While the player count bump might look like a sudden viral hit for the game itself, the surge is entirely driven by a clever technical workaround for a popular community project: the Undertale Together remote multiplayer mod.
Because Valve's marketplace officially supports remote play locally, players found a workaround to enjoy Toby Fox's single-player RPG in shared sessions. The installation requires copying Crashphalt files into the mod's directory and renaming Undertale's executable file to match the indie fighter. Steam's backend registers the process as launching RetroSpecter's game, thereby unlocking remote play functionality.
Developer Response
Reflecting on the unexpected traffic, RetroSpecter noted that while the project originally served as a stepping stone to full-time game development, it's "really cool" to see the title take on a completely new purpose. A similar mod for Deltarune has continued to drive stats upward for the free 2018 release.
RetroSpecter believes any free game with Remote Play enabled could have filled the role, but Crashphalt lucked out through sheer convenience and availability.
