HOW THE HECK DO YOU GET INSIDE VEHICLES?????
Oh my god....I basically followed Darth Vader, while playing a trooper and when Luke got passed vader he came at me and killed me. Just a heads up.
This will be your "ENTER" Command in the Control options inside of the "CONTROL OPTIONS" portion of the game set up.
That gets you in and out.
Cheers!

The E key will allow you to enter a vehicle. As far as I know the heroes will not attack each other.
