Want to try the new DayZ Stress Test branch?

Here’s how you activate it in Steam:

• Open Steam
• Right Click on DayZ
• Click Properties
• Click on the BETAs Tab
• Enter beta access code to unlock private betas: ireallywanttotest
• Select the beta you would like to opt into: stress_test –
• Wait for the Stress Test branch to download
• Play!

I am reading online that there is a Single Player Offline mode and this is also how you can get in on the very short stress test gameplay sessions from the developers.

Also, make sure to report any bugs on the official DayZ Feedback Tracker
