While this is not a full game on its own but rather a mod for ArmA 2, it could still be the best zombie experience ever. I think using the word ‘realistic’ is the best way to describe this game. ArmA 2 is highly praised for its extremely realistic gameplay and DayZ continues that theme, only this time its with zombies.
Played out on a 225 square km open world, its a multiplayer online game where each server will only support 50 players at a time; you might walk for hours without actually meeting anyone. Players start with absolutely nothing, not even a map; scavenging is rule number one in DayZ. Group chat functions are available and can lead you to meeting another survivor and helping each other out, or a bandit tricking you into your untimely demise.
Its an extremely brutal game, with the average player’s life expectancy only at around 4 hours and zombies aren’t the only thing that can kill you, you need food and water to survive and other survivors that has decided to become bandits is also a constant threat. On a positive note, you can always leave a game and continue at the same spot with all your equipment.
The objective of this game if it wasn’t clearly stated above, is not about scoring the most kills; its about survival and the interaction between players when everyone is gunning for the same thing. You can download it here, you will need a copy of ArmA 2 to play it. Its still in its alpha stage so expect quite a few bugs.
