@Bawbz asked me to make a something special for his amazing Spellbringers Map project and was also so kind to let me share it with the Hive community.
He asked me to make a ballista model beginning last year and in summer this year asked me to make him a mobile bunker.
The models are custom made in Milkshape3D and finalized with War3ModelEditor, RMS, Notepad++ and old Oinkerwinkle tools.
The models are a little bit different from the ones you can see in the project. I did this so people can an easier time importing them, the models fit together with standard wc3 models and that the models that are in the project can set themselves apart nicely. These changes are only aesthetic and the models have the same set of animations and perform the same.
