This is kind of based off another post I saw but just some interesting ideas on how vehicles could be cooler. First up, along with modeling the interiors, maybe a way to move around within the tank in a more interesting way. For example, moving from driver to gunner would have you move out of the drivers seat and climb up into the turret. Additionally, an idea I had was that every reload in a tank took the gunner out of the sight and gave a cool first person reload animation yk grabbing the shell and loading it in.
Here is another similar idea. Have the commander be the one controlling the turret movement and the gunner is in control of reloading and pressing the fire button. It would require the commander to line up the shot and yell “fire” to tell the gunner to shoot. This could make armor a more intense cooperative experience. This could also allow the gunner to see an awesome shot of the kickback of the barrel. Just a thought
