Sumrak released an updated version of the DayZ: Namalsk addon on the nightstalkers.cz website. This small "patch" can be added to the Namalsk mod folder when you want to play DayZ zombies on the Namalsk map when you are also using the DayZ mod. Do not install this addon when you are not using DayZ at all!
Quote Sumrak : DayZ: Namalsk is the addition to the Namalsk Crisis Update 2: Pathfinder.
DayZ: Namalsk is adding the whole new aspect to Namalsk island. Adding DayZ modification support allows to the players, who host DayZ servers, run DayZ mod on Namalsk island with all kinds of improvements and additions, which DayZ: Namalsk offers. DayZ: Namalsk is not only focused on the support of DayZ modification, but it is also trying to focus on the new features, which will a bit distinct from the original DayZ and brings more challenge for the survival in the harsh environment of Namalsk. Altought all has been properly tested, some things will be noticable after a longer period and gathering feedback is necessary to polish things up (that is mainly about the loot tables).
