After you’re done scanning a sector in space, you’ll see the available missions. Select one and tap Start Mission.
Be aware of the powerlevel of the mission, as you might put your crew in danger if your ship’s powerlevel is too low!
Once the mission starts, you’ll be given choices to help your crew in various situations.
Watch out for their risk level, and keep in mind certain skills can help you with different choices!
Once the mission is over, you’ll be shown your rewards and/or losses depending on your choices and performance.
