DayZ Patch Notes: 1.16 Update, Latest Stable & Experimental Changes

By James Wright

The DayZ developers at Bohemia Interactive are constantly releasing new updates to the game. This is why it's worth keeping track of the latest patch notes so you know every small change to the survival sandbox as it happens. On this page we'll be tracking the patch notes for the game.

It's worth noting, the game has TWO sets of patch notes. The first is for the game's stable servers. That's the version of the game most commonly available on ALL platforms. In addition to this DayZ also has experimental servers, where new features are tested ahead of their official release.

Generally speaking, the stable patch notes don't change all that often, but the experimental patch notes will undergo constant tweaks as the team look to make sure everything is working perfectly before being officially released to the wider population of players. Keep reading for a look at the game's latest patch notes, regardless of what servers you choose to play on.

What Is DayZ Experimental?

Like all good online games, DayZ has a testing ground. Another server if you will that allows the devs to roll out updates and trial changes before they push it to the main game.

This way, the developers can be sure that when they do roll out any big changes to the main player base, it's been thoroughly tested for bugs and balanced appropriately (as much as they can, anyway).

How To Play DayZ Experimental?

If you're on Steam:

Right-click DayZ in your Steam Library and select "Properties". Now go to the "BETAs" tab. Select if you wish to opt into or out of the Experimental version.

If you're on Xbox:

You can download 'DayZ - Experimental' from the Xbox Live store.
