what is dayz experimental

DayZ Experimental is a separate, unstable test version of DayZ where developers can conduct tests for new patches before releasing them to the standalone version. It is an extended version of the game used to test new features or game fixes before they release the changes to the standalone version. In other words, the purpose of the Experimental branch is for the development team to experiment with builds in a larger userbase than their internal QA. To play DayZ Experimental, players need to set their client as Experimental. Patch notes on DayZ Experimental can be found on the DayZ dev-hub.
