A few minutes ago a new Developer Update came out which confirms the date for the PTB and anticipates all the news that will come into play with the Mid-Chapter!
All the changes below will be possible to test tomorrow March 7th in the Player Test Build on PC!
REPAIR CHANGES
As you well know, every time a new survivor starts working on a generator that another survivor is already working on, the progress bar turns red, this is because a malus is added to the generator's completion speed. From the next patch, the completion penalty is increased from -10% to -15%, thus increasing the completion time of a generator made by four survivors from 28 seconds to 36 seconds.
The percentage of progression that survivors get when they manage to make a "great repair skillcheck" from 2% progress (about 1.6 seconds worth of time saved) to 1% (about 0.8 seconds worth of time saved) has also been decreased. But the blood points you get by making a great skill check from 150 points to 300 points have been doubled.
Due to these changes, two perks have also changed:
- Prove Thyself: Increased the repair speed bonus from 10% to 15%.
- Stake Out: Now increases the great skill check success bonus from 1% to 2%.
MAP CHANGES
In this mid-chapter patch many changes have been made to the maps including tile tweaks, modifications or replacements of some loops with the windows, spawn of the windows, size and layout of the maps. Below you can see an info-graphic of the various changes made:
