How to Install DayZ Mod for Non-Steam Versions of ArmA II

Aug 31, 2012


So you bought a non-Steam version of ArmA II? Installing the alpha version of DayZ is no easy task, as it is an alpha. This guide should help those who bought through¬†Retail, Bohemia Interactive’s store, or (the version this guide is based on).

To be clear, DayZ mod requires ArmA II: Combined Operations which contains ArmA II and the expansion pack, ArmA II: Operation Arrowhead. You could also use ArmA 2 Free + Operation Arrowhead to play DayZ, but it isn’t recommended (via DayZ Wiki)

I’ll be covering the version of the game, but it will apply to the other Non-Steam Versions of ArmA II to help get DayZ installed.¬†
