I came across some rare images that I hadn't seen before. They're scattered in multiple places and I had to dig into the Wayback Machine to get some of them, so I wanted to make a post here putting all of it together. Until today, I had no idea that box art had been finished for the Hadley's Hope set or that a Resurrection Newborn head playset was planned.
A post on this Star Wars collecting forum claims someone has a painted prototype of the Newborn set, but I haven't been able to find any images.
Aliens Action Set
Featuring all figures and vehicles from the three Aliens Micro Machines collections that were released along with an unreleased headless Ash figure. Ash, pictured in more detail below next to an alternate, unused Ripley sculpt, was apparently deemed too scary for children. (Yet they had no problem recreating the chestbursting sequence in the Alien Transforming Action Set?) Outer World Station Action Fleet Set
Mega-sized set of Hadley’s Hope in the style of the Death Star, Ice Planet Hoth, and Yavin Rebel Base sets they released for Star Wars. Figures to be included were the queen, Ripley in the power loader, Gormon, and Bishop. Jorden Family Daihotai Tractor
Was going to include Newt and her facehugged father along with an LV-426 landscape display stand.Alien Resurrection Newborn Transforming Action Set
The first wave of this line came out in 1996, one year before Resurrection, so it only makes sense that they were planning to incorporate the new film as well. From what I can tell on the blueprints, the bottom of the interior is the scene where Perez blows up an Auriga escape pod. I can't make out what the other two levels were going to be.Predator Action Set
A collection of the Predator figures and most of the vehicles from the three Micro Machines collections. For whatever reason, the Predator ship and the truck from Collection 3 are not shown, and an unproduced white truck from the guerilla camp is in their place.Unreleased Predator Ship 1
According to AliensCollection.com, the design of this ship was from the Dark Horse comic, Predator: Bad Blood.Unreleased Predator Ship 2
Also from Predator: Bad Blood.
