Road of the Dead
You are mining your business on your shop when you heard the news about Martial law. Suddenly, the government declares martial law. you know that something is not right, so you try other stations to find out what is going on. You were right all along as the whole city is infested with zombies. The city is not safe anymore, but the military want to contain the whole situation, so they don't want anyone living the city. You know that you would eventually die if you can't go out of the city. You will die either case, but you have a chance to live if you can go out of the city. Drive your car out of the city. The idea here is to get as far as you can as you can't do it in a single try. You earn some points based on the zombies you killed and the distance you traveled. you can use the points to upgrade your car. This can't be finished immediately as you would need to try over and over again until you successfully got out of the city. You can unlock other missions in the game once you got out of the city.
