Custom version of the UNSC Grizzly. About 90% of the parts used are from the UNSC Rhino set with some other extras added as fillers to get some of the slope shape details in as well as strengthen internal structure. I really wanted to stick within the parameters of making a custom set out of a specific amount of parts, and given those limitations, I'm happy with the result. It is missing some details such as the extra pair of treads on the back, but given the size scale, the proper treads would have needed to come from the ONI treaded bike set or the COD snowmobile. I have none of those sets so I had to leave it out. The other thing I just could not figure out out how to do (given the limited piece parameters) is get the rocket launchers on the sloped sides of the turret. I had to sacrifice some function for form. But enough of blabbing on, please enjoy the result.
