Hello Survivors,

Today we are launching the first Experimental Update for the Patch 1.02. We know you are more or less patiently awaiting every single one of our post-launch updates, and we’ve been quieter than usual while ramping up to this one. Focus with 1.02 is the return of two high tier weapons and one vehicle. Let’s get into the highlights of this update:

Olga 24

Once a high end, “Executive” level car, the Olga 24 is a four door Sedan easily able to reach top speeds on the Chernarussian roads.


The select-fire rifle LAR is used by specialized military forces. It comes with a 20 round magazine, using .308 caliber bullets.

M70 Tundra

The M70 Tundra is a bolt-action hunting rifle using .308 caliber ammunition.

  • It is highly recommended to use the Steam client option to verify the integrity of the local game cache to avoid corrupted data after downloading this update.
  • Consider de-fragmenting your HDD after downloading large updates.
  • Updating a moddable game and its platform is not without risks. We use various methods to communicate upcoming changes to our awesome modding community. We also co-operate directly on troubleshooting, and we offer an opportunity to test updates via our Release Candidate tests. Modders, server administrators and other members of the community do their best to prepare for updates and to address issues post-release as quickly as possible. Please be mindful of some interruptions (especially in the first hours / days after a release) while we all work to improve the game together.
  • In case of problems, please check the Bohemia Interactive support F.A.Q.DayZ F.A.Q., or BattlEye F.A.Q.
  • You can help us to further improve the game by posting your feedback on the Feedback Tracker.
