DOOM (2016) (a.k.a DOOM 4) is fantastic. The nostalgic factor with the classic levels was very nice, even though finding them was very annoying in some levels. I admit I cheated by watching where they are since I didn’t want to spent hours watching every inch of the level. I prefer to shoot and kill monsters instead! While playing a crash made me loose all the upgrades, I could still see the unlocked levels and use all the guns but all the upgrades were gone. Thankfully I was at level 5 and I didn’t find all the secrets and I would replay them anyway but still, I lost many hours. When I searched about the issue I found out that this specific scenario happened to many players. There are already threads for this so I didn’t post it earlier but I decided to warn the Doom players also.
How to backup
The base path where the save games are is: %USERPROFILE%\Saved Games\id Software\DOOM\base
Inside the savegame folder you can find a folder which name is numbers. Every time you stop playing, go to savegame folder and zip the entire folder (to also save some space).
How to restore a backup
The restore has one step more than the backup. The first is to extract the latest zip to your savegame folder. The second is to do the same but in the temporary folder. In the base path, there is a generated folder and then a temp folder. Inside temp folder you can see the same savegame folder as in the base path. Extract the zip also there or better delete existing folder and then unzip.
A savegame for finished game
The following file is the savegame for the completed DOOM. It has finished single player, all guns with full upgrades, all secrets found, all collectibles, all runes upgraded and all challenges completed. If you lost your progress, you can use this save file. First slot is the corrupted one so don’t use it. Also, the number is not mine, I found that by searching a number that is used in another thread. You have to rename the folder if it is not the same id. I have 25 save files while backing up my progress. If someone doesn’t want everything unlocked but prefers to continue at a point close his progress before the crash let me know through a commend and I will provide a different savegame.
