The Emissary model is the Mirror Universe version. The MUAC is the only ship I have used that can use the Emissary Skin, even though tbh I tend to stick with a combination of the Avenger skin with a few mods.
The Emissary is the original model of the star cruiser, Avenger and Vanguard alternative designs.
The fleet star cruiser now has its own design with once again Avenger and Vanguard as alternative model.
Now my question: are 4 models available for customization, or is the beautiful and sleek Emissary design unavailable ?
For some reason that seems the case only for the star cruiser, Prometheus, Intrepid etc all offer the baseline design as customization option in the selection screen.
