Hi! I preferred to create more detailed placeholders than use a model from the Asset Store (due to import issues, among other things). So the previous aircraft has a new design 
First, some sketches of the vehicles in the game:
The main character has a name: The Balduzard aircraft. Under the wings, you can see the three different weapons available (red for standard, green for nets, blue for EMP).
The TGV.
The club car has a landing pad to reload ammo and refuel the Balbuzard.
Two cars also have defense turrets. I hope to learn how to code that later in the course.
The Amazons
Drone Type Marpesia: it carries a bomb and could drop it on the train. You must shoot it first otherwise 
Drone Type Lampedo : A drone with a powerful cutting torch. Its purpose is to breach the hull and expose the crew to other drones’ firearms.
Drone Type Penthesilea: With a machine gun, this drone is here to shoot you. Or the crew if exposed.
Drone Type Hyppolita: The biggest drone with two huge machine guns. It could land and drill the ground to secure itself in front of the train. Massive and deadly threat 
Mothership Type Thalestris: Last but not least, the Mothership is full of small Amazons and should be neutralized or new waves could arrive soon.
I reworked the terrain to be more related to train-following gameplay. And there is a checkpoint tunnel placeholder to close the level (or part of the level).
For now I need to sleep but I will upload a video soon
