You know.. The AvP mod is cool and everything but, you can't just use only the mod to build the ship, you have to use your imagination a bit more, for exemple, I know minecraft doesn't have computers, but it's not because the AvP mod got terminals that you have to use them for the Nostromo, as they are not accurate at all from the actual bridge...

Use clay, brickstone, iron, stabs, fences, Idon't know... Add some details ! Because otherwise it's just a déjà-vu that lack imagination, don't stick with the AvP mod, minecraft as so much more potential than being stuck with 1 mod, combine multiple ones, use vanilla minecraft, add some details, I'm sure you can do far better than this.
