Got a gato done up real quick since it was available and will allow me to build up the gameplay test bed real real quick for testing simulations.
Water simulation addons get harder and more intense in complexity and such the smaller they become ie breaking waves, spray etc.
Gonna get it rigged and animated tomorrow. Not gonna worry about an interior for now and I didnt bother with the 40 or 20mm deck guns.
