undead massacre

Fill the streets with blood and intestines of the undead!!!
With up to three friends you get dropped into a city to find and rescue any survivors.
Supplies are limited so you have to scan through the hordes of zombies for weapons and ammunition or anything that might help you to get through this mess.
Find some gasoline and light up fires, so the chopper can land closer to your position.
Rescue as many as you can!
Survivors will reward you with new body parts for your avatar, as well as some ingame money you can spent on upgrading your skills and tools.
