It was only just released on Epic today, at the same time it went free.
That’s not enough time for WeMod to automatically detect the game exists on the platform. WeMod detects a game’s existence and adds it to the WeMod library depending on how many people at WeMod own the game. It’s a system that prevents the library being spammed with junk, abandoned, and asset flip scam games. Earlier today, zero people owned the game on Epic.
