At the Eurogamer Expo today, the dead of developer for the popular DayZ, Dean "Rocket" Hall, stated the DayZ standalone will be out by the end of year. He explained the importance of getting the game out quickly as the threat of copycat games, such as War Z, could be hurtful to his game. Hall also discussed some of new elements he wanted to add to the game including using household items as weapons, spread of diseases through feces and vomit, and being able to craft healing items like a splint.
DayZ is a mod for Bohemia Interactive's military shooter, ArmA II. Released back in Spring, more than a million players have jumped on DayZ making ArmA II one of the better selling PC games in the last several months.
