So the missions include different aspects of the gameplay, but some people can't do/ don't want do some thing. And almost always we must complete missions in order, but when you can't do the task, the time expires and what happens- no tokens/ xp .
So my idea is when you click with MB1 on a mission, on it's place it will be written: "Do you want to skip the mission for 200 BE?" and below that - "Yes" and "No". When you skip it the mission will become the last mission to complete( you complete all the other missions and then the skipped one). That's it.
When you buy a pass you will get 5 free skips.
