OK, so I've just brought Arma: CO

[Samwells 1]

What now? I've downloaded Arma: CO onto my Steam account.

I really want to play DayZ.

What's my next step?

[jaytmuk (DayZ) 621]

Install them, Run both Arma & Arma OA at least once then download DayzCommander and use that to Install Dayz

[chakijz 174]

Download DayZ Commander from the main page, it does everything for you :)

Once set up and ready to roll in Dayzcommander type in the filter box to the left Zombieland 100+, Looks a good server to start on, very busy and always daylight. (not been on it myself yet but saw it in list and seemed good for a starter player)

Or you can do it like me and install dayz manually and get screwed over

Yep i got into Dayz bout 5 months ago before Dayzcommander and Sixupdater, Was a mare back then to install and try to get on a server lol

All you had to do was download the files and put them in a folder called '@DayZ'. o.O

Anyway, like jay said - make sure you run each game once before installing DayZ then use DayZ Commander. It downloads and installs the mod for you.
