I want to help you in this project.
This game is very very cool but it need some conceptual military design (simple, solid, functional) and as it is a UFO it must be some mistical. For now it's desing is scattered some from military some from children
.
I have some suggestion about design. If you interested I do all what I can for this super mega extra game.
I have some 3D models for this game (I was fun of XCOM) and ready to give it to you.
