I didn't have my LOS books handy, but at some point they mentioned the AI of the Machines would redesign the nightmares to better represent the nightmares of the Aliens they were fighting. While the "Terminator" scheme is pretty popular, other attempts to make them "real" skeletons, demons, or even just coloring them differently for camouflage or to distract the enemy are encouraged.
|A golden Nightmare, much nicer in person|
|I don't like the skeleton work, but I won't change it until I reference the suggestions in the book.|
|Pretty much your stock Nightmare|
|Electric Blue Strikes Again!|
|A Stealth Nightmare. Just slightly darker.|
NEXT UP: More robots... and some golfing accessories.
