DayZ's forthcoming alpha testing period is for dedicated fans only, with creator Dean Hall warning fresh adopters that it may be 'a recipe for disappointment'.
The alpha is due to release through Steam Early Access before the end of 2013, and while it will be available to the general public, Hall has said it might not be a good idea for all players to jump on board immediately.
"I really can't emphasize enough - this is going to be an early access project on steam," Hall wrote on the official DayZ site.
"It's a true-blue alpha. Massive areas of the engine were entirely reworked, involving a large team of people over the last 12 months. Much of what these achievements will enable won't be seen for many months - so I really plead for anyone who is on the fence to take a skeptical approach - watch streams, read reviews, watch some let's play and form your opinion. You could always come back to the game in three, six months time and buy it then.
"Buying early will be a recipe for disappointment," he continued. "It's a chance for those who want to be part of that whole process."
Hall said that the Early Access edition should only be purchased by those interested in monitoring the game's development.
"For them, the process is as much as part of the game as the whole experience. For many, this is the opposite of what they want. To enable a smooth launch, we really are targeting it at a core audience who want to get deeply involved in a very barebones experience that is a platform for future development."
A lengthy gameplay video was released last month, showing the game in a pre-alpha state.
