PTB stands for "Public Test Build" and is a chance for players to be able to test upcoming features. Currently, this feature is only available to players on Steam.
To join the PTB, follow these instructions:
- Right- click Dead By Daylight in your Steam library
- Select "Properties"
- Head into "Betas", then select Public Test Build from the list
If this option does not appear, then it is likely a PTB build is not currently live.
I lost progress after switching to the PTB.
The save data that is used on the Public Test Build is a snapshot of your Live account from several days in the past, which is why it may seem like you have lost progress.
Once you switch back from the PTB to the Live version of Dead by Daylight, your progress will be returned to the way it was before switching. Your PTB progress remains on the PTB only, it does not switch back to the Live version.
