Crashphalt

Crashphalt is a free multiplayer indie game where players use ground-pounds to generate seismic waves, attempting to knock opponents off-screen. Released in 2018 on Steam, it languished in obscurity for years before recently finding an unexpected audience.

The game's fortunes shifted when players discovered it could be repurposed for Undertale online multiplayer, turning a forgotten title into a sudden hit. This second life has driven fresh interest, with the game now carrying an overwhelmingly positive user rating on Steam despite its quiet original launch.
