Yup. They take place just shy of 60 years apart, with 2 in 2179. 3 happens very shortly after 2. Resurrection is a century or 2 later.<br/><br/><br/>Those are the best ones, anyway. Though Winona is cuuuuuuuute in Resurrection.<br/><br/>(Timeline-wise, Prometheus and That Other Thing take place before Alien.  But let's not go there.)
