The recent release of patch 1.1 for Sega's horror game Alien: Isolation has caused some issues for PlayStation 4 users. Specifically, after applying the update, some users have reported having trouble playing the game's fifth mission. The Xbox One and PC versions are apparently unaffected.
Sega writes on its forums that is is working with Sony on a fix, though it's unclear when this will be ready. In the meantime, the developer has removed the patch for PS4 owners, and published a set of instructions for how to revert to an earlier, less buggy version of Alien: Isolation.
If you follow the instructions below correctly, your game should work fine, Sega said.
Uninstall Alien: Isolation from your PS4, being careful to retain your save games.
Reinstall Alien: Isolation to your PS4.
Download and install patch v1.01 from the PlayStation Network.
"Many thanks for your patience and apologies for any problems you have experienced," Sega said.
Alien: Isolation's 1.1 patch was released on Wednesday, November 12 across PS4 and Xbox One. The update addressed issues with the playback of certain cutscenes on those platforms.
