Overwatch: Recapture

Hi, I present to you my first PvE mission called Recapture. It takes place on Midtown where you have to hack 3 Null Sector outposts then escort the payload to a train station. However while escorting payload it runs out of fuel. When you arrive at the train station you have to protect the payload until it opens the door. After all of that you just have to eliminate all elite Null Sector units inside the train staion.

I hope you will all enjoy my mission.
You can also tell me what to improve on this mission and future ones. :)
