Dean Hall's zombie survival mod DayZ is slated to increase in difficulty once new vehicles and weapons are introduced, including helicopters and small aircrafts, the developer confirmed in a recent Reddit AMA.
"The plan is to increase the difficulty significantly as new functionality comes online (such as throwing and improvised weapons, hunting, bow and arrow," wrote Hall, who added the game is still 80 percent away from being finished.
Vehicles will be designed based on the same in-game architecture used for items and weapons, allowing for attachments to be made, Hall continued. Additionally, the physics system is being replace for items and the same middleware will be used for vehicles.
"Bases will take longer. Barricades will happen first," he said. "I think helicopters and small aircraft will be important. But they should be very complex to maintain."
Studio Bohemia Interactive sold over one million copies of Dayz within four weeks of the launch of its Early Access release. The title's alpha released in late December for Windows PC for $29.99.
