DayZ 1.13 Experimental Update is Slightly Delayed – Patch Notes

Bohemia Interactive has announced that the experimental update for DayZ is being delayed. This update is much anticipated because of the new additions coming to the game, including weapon, burst fire mode, new scope, 60-round mag, and most importantly, new types of infected zombies. According to Bohemia Interactive, the Experimental Update should finally arrive in 30 minutes from the time of this writing.

As we said above, there will be new types of infected and will consist of Heavy Soldier, Military Officer, Runner, and Heavy Police. They will probably hold some items of high value that will speed up the gearing. With the zombies having lots of tweaks in the past, it feels like DayZ is slowly evolving and heading towards a better place.

Furthermore, there are tons of bugs and issues fixes that can be found below.

I am ANGE1K. I started playing video games a long time ago. In a blink of an eye, I became a hardcore gamer. A couple of years later, I traversed to the professional Counter-Strike 1.6 scene. After the competitive ERA, I managed to find the gaming industry amusing and started working on FGR. 8 years after founding FGR, my mission remains the same. That is to discover secrets within the gaming industry, create guides for all the games I play, and provide you with some important news. Oh, yeah, I post tons of patch notes too. At the time, I play everything that seems reasonable to play, make content about it and help gamers to the best of my abilities. P.S. Last time I counted how many hours I've spent in video games turned out to be 13+ years. And that was a long time ago too. Almost 24/7 in front of PC.
