Woah, more survivor slots?! That's crazy, now you can rescue more people without feeling bad that they're not special.

Features:
80 extra
60 extra
40 extra
20 extra
10 extra

This will only work once you max out your HQ, so you have to actually progress it to use it :^)
Choose only one, and once you go above 40, I recommend not deleting the mod, otherwise I don't know how the game will react to it.
