it is, it just takes a lot of fancy math and vertex movement. a lot of work, enough where if i was lonewolfing it or working on a small team, i wouldnt want to try it, there is more important things that will take long enough as is. i'd just have a few varied ways of letting him be dismemebered and leave it at that.

id also guess if you were using a 3rd party physics engine like havok it might be doable through that in some ways, but that kinda integration would also be kinda tough to do as well.
