an idea i had while overdosing on caffeine lol.
Basically during tuesdays or any otherr day in a week a notification will be sent to all players that a cargo train will arrive to the active city, and the location will be shown on the map. the train can be stopped either by placing a bomb on the rails, Hijacking the conductor's seat, or by killing the conductor with a gun. after that you have to get in one of the train cars to take a loot bag. once you are finished you have to go into a hideout.
police will be called when the train is attacked obviously and after some time the train will resume once again albeit unrobbable.
Kazutoki Kono himself bestowed me the power of all eight ace combat protagonists whenever an enemy seasparrow shows up
