Hi Mr-Mortification
I'm sorry, but this model is not suitable for games - it's over 0.5 million polys. Besides that I cannot fulfil your request, because it has a complex animation rig which cannot be easily exported to some other format. It's not a "soft body" which can be used as skin, it's a machine - there are pistons, elastic cables, parts that rotate only in certain axes and dependencies.
Perhaps you'll find this interesting:

Thanks for interest and sorry for late response.
