Is it true that Shotgun T-Dolls are heavier than others?

It is partly true. Commander, we shotgun t-dolls are based on Sangvis Ferri's technologies, and special armor corpusculums, so we are developed much more solidly than normal t-dolls, that's why we are slightly heavier as a matter of course.

If you need more data within authorized security level, I'll find out for you.
