I was using my Bot Factory to make an APU from Matrix: Revolutions. I didn't have the parts I wanted, so I just messed around with a few "greeble" parts. After about 1/2 hour, this thing showed up. IOt was just a coincidence that it turned out looking like an egg. So as an altenate name, I dubbbed it "Easter Egg".
The E2 was designed for security and light combat. Mechs like these were mass produced when being onslaughted with firepower. the exosuit isarmed with twin laser canons mounted on ech arm. Another advantage is that the mech has arms that can hold a variety of object, making the suit more versatile than a simple light combat mech. It has also been used for construction purposes.
