For those who like the action, there are some changes that affect the Cargo Missions. There are 3 levels of difficulty now. So far you have played the easy level. But level affects the time you have to complete the mission and the number of zombies to kill. You get paid better by completing more difficult missions. The limit of 20 is removed. The crew can be formed of 3 members (minimum), and max 5. A random member of the crew will be asked to pick the level for the mission. More on the website.
