Answering the brief’s requirements
I’m going to design a fast scout ship that’s able to defend itself and rescue colonists under threat. Defining your universe’s technology will shape your design. As an example, what’s the propulsion technology? A fast, fuel-intensive method would mean less space for supplies. Perhaps it’s achieved with a specific drive that takes up more room than conventional engines?
In a game that features a range of ships, it’s crucial that they have distinctive silhouettes. Think about basic design language: for example, rounded edges can be seen as safe shapes, so use them for passenger craft. My thumbnails fit the brief because their flat undersides would be able to handle planetary re-entry. The wings convey manoeuvrability and speed.
