So in this world, the Autobots and Decepticons have made peace. And together with them, you created a group called the "Interdepartmental group 'Your Own'". Well, there you investigate a murder and find the perpetrator or culprit for it.(if anyone doesn't know, then look at YouTube and you'll understand) You are the person whom you feel the aura or pieces of the past that help you find the culprit. Retch and Knockout these doctors will naturally examine the body to find out what the victim died of. And Arcie is also investigating, Bumblebee and Smokescreen are to be spies, Ultra Magnus and Soundwave are punching through the database to get additional information. Well, in short, so you can figure out for yourself what kind of attack and all that :)
