What I'm thinking of is something like a motorbike-style body modified to use reverse-joint legs (a.k.a, bird-style legs) for its main form of locomotion that's only slightly larger than a large motorbike. Such an example of a vehicle exists in Shadow the Hedgehog (GC/PS2/Xbox) and such was the inspiration for the SL vehicle idea. Unfortunately I was unable to obtain any screenshots of said vehicles (The GUN Jump/Attack Vehicles; Jump Walker being the green, unarmed one and Attack Walker being the Autocannon-toting blue one in the reference pic) but I was able to extract 2D sprites of said mechanized rides from the Shadow Divine Sheet.
(Unfortunately there were no front nor rear views of either GUN Walker in the Sheet.)
I'm not necessarily asking for an exact SL counterpart to either of these mechs, but they illustrate the kind of SL vehicle I'm looking for. Of course I'd like for it to be low-lag and not be able to jump super-high. (The GUN Jump Walker should be able to jump up the height of a whole flight of stairs whereas the GUN Attack Walker should be only barely able to jump.) They should also be able to hover and their walking speed must be no faster than normal on-foot walking speed.
As I said, I am more than willing to help test prototypes of the mechanized walkers and issue feedback on any bugs/glitches/etc. on it in return for the development thereof. You can either respond here or IM me in SL. Thanks! OuO
