honestly, i dont think theyre spoiling much. i have a feeling there is going to be A LOT more going on in this film than 20th Century is letting on to! theyre showing JUST enough to let people know its an "ALIEN" film and that the Xeno WILL be present... what they havent revealed is exactly how far down the rabbit hole were going to wind up going in relations to answers to Prometheus, new questions that will be posed, exactly what caused David to commit genocide, what happened to Shaw, what the Xeno actually IS etc etc. basically everything released in marketing thus far (outside of the prologue on Alien Day), there really hasnt been much revealed about the film in terms of details and story PAST the alien itself. Hell, weve BARELY gotten a glimpse of ONE Neomorph.
