A new patch for the PlayStation 4 version of Alien Isolation is leading to issues with save games and causing the game to crash, according to online reports.
Users began reporting the problem shortly after the release of the game's 1.02 patch last night, with some stating that they have been unable to continue playing the game due to a CE-34878-0 crash bug.
One Twitter user said that the title update rendered the game "unplayable".
"We're aware that some people are experiencing problems on PS4 with Patch [1.02]," Creative Assembly said in response to the reports. "We're looking into it now and hope to have an update shortly."
The patch had been designed to resolve problems with the game's juddering cutscenes. It is also available to download on Xbox One, although issues have not been reported on that platform.
UPDATE: Creative Assembly has removed the 1.02 patch from PSN and advised players who are continuing to experience problems to delete the game and reinstall.
"We've discovered an issue with the latest patch (v1.02) for Alien: Isolation on PS4, where some users are having difficulties with playing Mission 5," the developer wrote. "We're currently working with Sony on a fix and will have that available as soon as possible.
"In the meantime, we want to make sure that this issue doesn't prevent you playing Alien: Isolation. With this in mind, we've removed patch v1.02 from the servers for PS4 only. If you have already downloaded patch v1.02 and you are experiencing problems, please follow these steps to revert to v1.01:
1. Uninstall Alien: Isolation from your PS4, being careful to retain your save games.
2. Reinstall Alien: Isolation to your PS4.
3. Download and install patch v1.01 from the PlayStation Network.
"Your game should now work correctly. We will reissue a new patch for PS4 soon that will address the original cut-scene issues.
"Many thanks for your patience and apologies for any problems you have experienced."
