Question about custom mounts and other things

I wanna make THIS unit
~D ~D ~D

any one can help me with some basics things
thanks ^^

Yes...that can be done.

I have made walking 2 legged mounts...but you need to base it on a horse or camel skeleton. You will also need to make a new set of animations to make that skeleton walk in the way you want. Then just align the rider where the thing needs to be and you are done.

I used this approach to make 2-part walking droids for Metal Mayhem, so I know it works

uhh...it seems hard to do....Can I use the model of this unit? How can I make animations?

Horses are bigger targets and missiles always have lethality 1 if they make a sucessfuly pierce.
