From publisher blurb: Weather balloons. Swamp gas. Low-flying planes. We have all heard the excuses given by government suits, news hacks, and close-lipped military officers. But the truth, as they say – is out there. For decades, maybe centuries – even millennia – they have visited us. Short, thin gray beings bent on exploring – or maybe conquering and exploiting – Terra. They pilot starships that are technologically advanced beyond anything Humanity had in the 20th and 21st centuries: archetypically saucer-shaped but there are other shapes as well. Terrans designate these ships as "Unidentified Flying Objects" – or UFOs. This supplement allows you to combine such advanced alien craft, as well as their Reticulan crews, into your science-fiction role-playing campaign. We present you with eight UFO designs based on classic Reticulan spacecraft shapes from UFO lore. They come complete with high-resolution deck plans, color renders, and full game stats for the Cepheus Engine We also provide rules for generating Reticulan characters, as well as a general description of the Reticulan species. We also provide several Cepheus Engine variant rules appropriate for the starships included in this booklet. The background for this booklet is, by default, Stellagama Publishing's These Stars Are Ours! space-opera setting for the Cepheus Engine. However, we designed the booklet so that everything is readily and directly useable in any science-fiction setting envisioned by the Cepheus Engine™ SRD, Cepheus Light, and similar OGL 2D6 Sci-Fi games. However, These Stars Are Ours! presents significantly more information regarding Reticulans, as well as more Reticulan character generation options. We highly recommend that any Referee or player interested in Gray Aliens, or the default detailed background behind these UFOs, refer to this book. For the sake of completeness, we have also included three ships originally presented in These Stars Are Ours! – the Abductor, the Civilian Saucer, and the Military Saucer.
