You knew that DayZ has custom maps, right? As Bohemia labors away on the standalone version of DayZ, modders have been busy porting user-made Arma 2 islands into the zombie survival mod.

Namalsk is in the process of being ported by Sumrak, one of Namalsk's creators, and should be available for download here soon. In the meantime, here's a video of the map being tested in DayZ.
