Back up your own save files first!
1) They can be found at: C:\Program Files (x86)\Steam\userdata\your_steam_number\8870
2) Download my files from: https://drive.google.com/file/d/1j8oJ0EQ_DFPdfkVK8VpBIBhA1UKtl28x/view?usp=sharing
3) Switch off Steam sync, swop the folders content, load up the game, press Continue in either Main game or DLC.

If you want to beat the highest difficulties by yourself - it's quite doable, manageable and enjoyable (well, apart 2 or 3 fight sequence).

Nothing tickles your nerves like the invisible moments in the DLC or the ghost fights in the base game.


HOWEVER! There are some gamers who just want to enjoy the game AND achievements, so they might not want to go through all the troubles. Quite understandable. Thus - these saves, explained below.

You still have to walk through the last chapter, Sea of Doors, which takes around 10mins.


Auld Lang Syne
(Completed the game in 1999 Mode.)


Scavenger Hunt
(Complete the game in 1999 Mode w/o purchasing anything from a Dollar Bill vending machine.)

---------------------------------------------------------------------------------
By this point I have picked up 24 Audio Diaries. The 25th is behind this door.

Walk through the last interactive chapter, there is no fights involved, you simply approach Atlas and earn the difficulty achievement.


The Whole Story
(Collected all Audio Diaries and Voxophones in Burial at Sea - Episode 2.)


Taffer's Delight
(Completed Burial at Sea - Episode 2 in 1998 mode.)

I also included the folder with 100% base game. Do not guarantee it will unlock anything, but one can try picking up an audio diary or checking a sightseer - maybe they will unlock related achievements, who knows?
