It's a shame to let a good engine go to waste, especially when it can expertly handle a huge, beautiful open world. DayZ is the most obvious example, but Ubisoft clearly understood this as well when it made Far Cry 3: Blood Dragon , which used the Far Cry 3 engine to build an '80s-themed spoof that was just as fun as the original game. The Far Cry 3 Z-DAY mod sounds a little too familiar, but the gameplay footage and explanation from the developer might win you over.

To be fair, Z-DAY is not as much like DayZ as its title may imply, and modder GC Vos says the name will be changed to something more original. To start with, it's a fully fledged single player campaign, not a multiplayer survival mod and showcase for human depravity. It will consist of 12 missions "much inspired by games like Left 4 Dead, but with a Far Cry twist to them," GC Vos explains. It will also add a new soundtrack and voiceover work.

The video of the first seven minutes of gameplay is the most impressive, showing the player trying to stealthily make his way out of a zombie infested town. Far Cry 3 was really great at letting you explore huge environments, jumping in and out of vehicles, and letting you seamlessly shift in and out of stealthy and guns blazing strategies. These are all things that seem like they could be used really well in an open-world zombie game.

GC Vos promises that the game's ModDB page , where you can also find more videos, will be kept up to date with the latest progress. Z-DAY is set to release in open beta on March 1.
