Too Many Zombies!

Anyway, the world is full of zombies.
Nobody knows why this happens and where did it start. So anyone can tell just by looking at it that's at stake. Best is to get out of here.
Zombies pounce whenever they hear the sound. But don't worry. The great communicator will help you. Or you have to rake something useful, and then you use this to make something to against zombies.
No matter what anyone says, the most important thing is survival.

Survive the zombie world with your colleague. It's pretty simple. Shoot, build and craft. That's it! The most important thing to survive is cooperation. Probably.
