Ok so if everyone knows this, then please excuse the noob. I just started collecting animated and stumbled across this while transforming my Starscream. I tried searching for this hidden feature on google to see if anyone else noticed it. But I couldnt find anything. SO what is the hidden feature? cooler attack arm cannons. While im not sold on the fact that Animated Starscream has forearm cannons, as opposed to the upper arm cannons that he has in the show I understand that it was a choice made during the design and engineering planning stages. Anyway here is what i discovered. upon looking at SS arms, I noticed panels on either side of his forearms. I also noticed that the cannons seem to be on a track and that it looked like it could slide forward. LO AND BEHOLD they do and the panels pop out. Pretty cool huh? Here you can see what the arms look like normally and you can see the track that the cannon slides down. Look at the arm on the right. right below the cannon hinge, in the shadow you will see the purple color of the cannon. but look at the left arm. that slot is no gone. That is the track you slide the cannons down. by doing so, the arm panels will pop out due to the hinges you see holding them out. Ok now what the heck are these for? I mean it is kinda neat that the back panel does this and im not complaining. but what are they for? is this seen in the show?
