Bohemia Interactive and Dean “Rocket” Hall hoped to have the latest update to DayZ live yesterday but a bug discovered last minute that has caused unforeseen delays. The new content has been available on selected experimental servers since January 17th and was originally planned to launch across all Early Access servers sometime yesterday but the forum post was updated with the following:
The bug we found late last night was that corpses are unable to be
looted we are in the process of fixing it as we speak no eta yet sorry
The upcoming content is still available on the experimental servers but will not be available to normal beta servers until the problem has been resolved. The update promises to deliver a number of fixes and adjustments to the games loot table adding much requested items such as the Shotgun, Hacksaw and the introduction of the new area – the Coastal harbor town of Svetloyarsk.
For more information on the changes involved in the upcoming update you can check the official post here.
