>>8000366Nonnef's upgrade kit. The main feature is the new feet that make using the treads as a heel much much easier, and add a toe-tilt. There's also a wrist joint upgrade and a part to de-headmaster him but I don't use that because it still needs to be partsformed and I like the headmaster anyway. They also did some new guns for him but that sold seperately.
I'd absolutely recommend getting this if you can even find it at all.
