The Steel Lynx is, basically, a mini-tank drone with a huge gun. Except instead of treads or wheels - it has legs WITH wheels. For bonus crawling around action. See:
HereDobermen are now walker drones, and have big guns on them. I see them as kind of dog-drone, really. I'm having difficulty finding good pictures of them, but basically the dogbots from
Deus Ex 2. They clomp around, look kinda spiffy, and have guns on their back. Also, the first few seconds/loadingscreen splash
Here.
Remember that cyberspace designs are the king of Vectored Thrust drones. From the Dragonfly to the Dalmation, they've got hover-jets/fans/turbines to propel themselves around. I see the Dalmation as a sleek, fairly big(body 4, remember? Thats as big a a lynx). Kind of like a Predator UAV without wings, just 2-4 vectored thrust(Either 2 on the sides, or two front/2 back) engines to zoom it about. Like
one of these, only smaller, more compact, and without guns.
Hope that helps.
Holy crap, spellbinder's link is really, really useful. Was all of that stuff really in 3rd edition, and if so, where can I find it?
