So this is the UGPS unit I made .. Model by Halogoddess.. Simple and turned out really nice. Its just resting on top.. I pepped it at the stock scale.
Now it looks pretty close to the game version which looks like you could pop it off and hold it... But I have seen it where literally takes up the whole top of the arm like a cover to the forearm..
Update( Stopped by toys r us to look at some figures.. Mcfarlane sculpt it is more like a mobile device that is just locked onto the forearm)
I can't decide. What you you guys think?
