BRIGAND - NIGHTMARE revamps the original story of BRIGAND - OAXACA, adding in more difficulty and new features from the BRIGAND - PANAMA DLC such as woodcraft, traps, and voodoo-casting baddies, as well as a new optional map accessible from Chapter 6 on.
It's a lot harder than the original, meant for hardcore fans. Hunger increases 50% faster, and baddie AI now picks up items. There is also a partial Spanish translation included called NIGHTMARE (ES).
