Type:3D model (but if you would be so kind enough to provide it with textures already then do so. ) File type: Preferably .obj or anything that Unity3.5 can use. Theme:Any of the following would suffice. Cruiser:A massive ship filled to the brim with various weaponry and defensive measures. The biggest and baddest type of ship class. Frigate:A smaller and more agile ship,does not posses as much weapons as the Cruiser variant but still strong enough to hold it's own. Fighter:A small agile craft built for swift attacks. I'm giving free reign as far as design goes on whoever decides to make at least one of the listed above. I won't complain as long as it looks bad ass.
