It took me a week to rack up more time in DayZ than I did in a month on Skyrim. Civilization V has beat that record, but it's yet to catch up to my DayZ time. This game is scary and suspenseful and thrilling and very, very fun. The best moments for me are when you acquire vehicles. I have had
many good experiences with vehicles.
Installing it has caused much frustration for many people, so I'll post some instructions here that have gotten me into the game reliably since I first got it:
First launch Arma 2, then launch Operation Arrowhead, then install DayZ by extracting the files from here into a new folder at @DayZ\addons in the main Operation Arrowhead folder, then install the latest beta (94444), then paste the arma2oa.exe file from Expansion\beta into the main folder to replace the old one, then right click on Operation Arrowhead in Steam, go to properties, and in "Set Launch Options" type "-beta=Expansion\beta;ca;Expansion\beta\Expansion -nosplash -mod=@dayz".
