I've written quite a few articles about running and playing DayZ. Here they all are in one place:
- How to install DayZ (with ArmA 2 Free, Operation Arrowhead or Combined Ops)
- How to get on a server
- How to play
- How to stay alive for more than five minutes
- DayZ offline single player / practice / training / (not really) cheating
- How to fix a helicopter, the easy way
And here are a couple of articles about gameplay experiences. Whilst not exactly tutorials, they do give details of events which may prove helpful.
The most recent version (as of 11th July 2011) is 94700 and is available here:
There's more to come, including advanced gameplay tips, but feel free to suggest a topic that you'd like me to write about.
