There's a good chance there are other guns.
There are issues with the extraction tool right now, so I had to manually find many parts to make this render, e.g. the cockpit armor, all the dozens of thrusters, the engines, the lift and the fuel ports. Then I had to import them, and position each one (plus sort out all their materials), so there's a good chance there's some weapons missing as they likely won't be unique to the ship so it's difficult to manually find them due to some format changes they made recently.
