Day One patches to games in the digital age are becoming the norm. Prey is no different, as Arkane alerted us to its existence when we found out about the PC system specs. But now we are getting a detailed list of what was fixed as player preload the game–and patch–in time for the May 5 launch.

The patch, which weighs in at 1.3 GB, and players who have gotten the game early are getting the detailed notes of just what was fixed (via Gadgets360). These patch notes are for the PS4 version (pulled from screen grabs of the update list), so be aware that the PC and Xbox One patches may be slightly different.

Among the changes are frame rate and crash fixes, as well as weapon fixes to the Gloo Cannon, grenades and some Mimic abilities. Arkane game director Raphael Colantonio also tweeted that an audio problem from the demo has been fixed as well.

Here's the full patch notes, and since the game is not out yet, we'll throw in a SPOILER warning, just to be safe:
