Tabula Rasa's own bipedal instruments of death have made an appearance on the public test server, and, even in their unassembled form, we couldn't be more excited to see them.
A poster by the name of Seraph on the Planet TR forums went even further than we did, using his photoshop-fu to put together what the Grendel might look like fully assembled, just from looking at the parts sitting around the garage in Foreas Base. While we'd rather like to believe that it would be slightly taller and imposing, it seems like a pretty accurate mock-up from what we can tell at this point. But then, that's just the Grenadier's PAU. We've still got seven more to go!
