Wild Justice is a cancelled FPS set in an “horror western” scenario, that was in development in 2002 / 2003 by Primythive Studio for the Playstation 2 and Xbox. A playable prototype was created to pitch it to various publishers, but in the end Wild Justice had to be cancelled. If it would have been finished, the game could have been similar to Darkwatch, an horror wild west FPS developed by High Moon Studios and published in 2005.
Wild Justice was one of 4 prototypes that were created by Primythive, but it seems that the studio never found a publisher interested in their projects and sadly they had to close down without finishing any game. Only few screenshots and a teaser are saved in the gallery below, to preserve its existence.
Thanks to Floran for the contribution!
