Matt Filer, a modder, has spent nearly a decade creating modifications for the horror game Alien: Isolation, which critics noted could have benefited from a shorter playtime than its typical 20 hours. Filer expressed that the game should have concluded around the 10-12 hour mark. He released a new mod called Impossible Campaign, which allows players to finish the game in under a minute by altering the narrative. This mod introduces xenomorphs to LV426, preventing key events from occurring. Filer developed the OpenCAGE toolkit for extensive game editing and has experimented with various modifications. Alien: Isolation is currently available on Steam.
