Commonwealth of Decay for Fallout 4

A brutal OpenWorld survival experience for Fallout 4 inspired by State of Decay NIGHTMARE! mode.

Clear feral infestations from Commonwealth workshops before running out of extremely limited resources to handle ever multiplying hostiles. This experience is for players that enjoy proper survival challenges:

The Commonwealth is an open world with all areas unlocked and no base game quests.
All ~600 base game human race NPCs replaced with ferals.
~500 additional feral group spawn points.
~400 recruitable robot and human survivors.
6 new feral spawning systems.
Everyone is mortal.
Ferals can’t run in daytime, one tap to the head kills them.
Workshop noise and unsuppressed player shooting attracts ferals.
Deadly decay infection from feral contact.
Resources are 25% base with no respawn.
