In Zipline, you move people from cabin to cabin to help them reach their destination. You need to avoid hazards and traps to get them safely.
Along the way, there are many dangerous traps waiting for you but don't worry, all you need to do is draw a safe path for your zip line and avoid the dangers. Management might let you lose one or two passengers but if you lose too many of them, the mission will fail and you will be fired. So be careful.
