This was my attempt at an underwater base I have always had an idea of. However, It didnt exactly come together due largely to insufficient amounts of pieces, which are mostly from Bricklink. Hope it's not too bad. Base includes a small submarine and an underwater mech(my favorite).
About this creation
USSD stands for United States Submarine Defence, a covert and elite division of the Marine Corps.
I love underwater themed builds. I like your set with the mech, base and submarine. The mech is cool because you succeeded in combining hero factory Lego with normal Lego. Any tips for that? I don't have any good ideas on how to do that myself. Hero factory Lego has no studs so I find it difficult to integrate. Ps I noticed your pictures are quite fuzzy. Maybe use more light?
