NewsVideo Game Updates & Patch Notes

DayZ 1.04 is yet another successful update giving medical items a purpose

DayZ, not any Milsim survival, but THE Milsim survival developed by Bohemia Interactive has finally landed another vast update. It was fun to play it on the experimental branch, and the masterpiece has finally arrived on the live servers as well. Patch 1.04 is here, and it brings new varieties and gameplay mechanics.

This patch is probably one of the most significant patches in the DayZ history, ever since it left early access and entered in 1.0. Being this big, it first needed a couple of hours to be settled onto the live servers. The servers faced a downtime of more than 3 hours, which was another indicator it’s one of the most significant updates ever.

For the first time since 1.0, the game adds a purpose to all of the medical items, should you use them for cleansing a disease. But, it also adds a throwable stance for grenades, shuffling them in the mix.

DayZ is the survival military simulator in which you, as a player, are allowed to experience the sandbox environment, but also fight to survive. Scavenge, eat, drink, and lots of other mechanics including a PVP environment in which players may intentionally lose themselves.

Below you can find the update 1.04 highlights introduced within a video material.

DayZ is the game that packs a mixture of experience and adrenaline to the highest level. Engaged in a fight with everything at stake, whether you win or lose, it may be a dependent factor on your future journey.
