How To Beat Bumblebee
How to beat Bumblebee is really easy. All you have to do is run around while you shoot to avoid his mighty blaster guns energy shots and keep shooting him until he turns into his car form. When you see that, you'll see him make a force field over himself. After that defeat the enemy guarding the satellite (the enemies may occur different for other satellites). Then after that you scan the satellite and see a confusing video of Bumblebees air force attacking Bumblebee instead of you. Repeat the process and Bumblebee will eventually drop down and die.
Note:I'm sure about that moving around thing. I died three times with moving around when shooting. And don't you ever, ever ever ever never ever get close Bumblebee to melee attack. Even with max stats on everything you would die from the extreme power of his energy blaster.
