The Aliens Drop Ship and APC, and the Alien Space Jockey and Space Jockey Ship, have long been requested as toys. You may have to keep waiting for toys of them that are in-scale to 7-inch figures, but if you’re good with versions that are slightly bigger than Micro Machines – at around 6 inches tall – NECA is making them happen, and is planning on many more fan-favorite vehicles down the line.
I’m not sure 6 inches will be quite enough for fans who had more nefarious purposes in mind for the Giger designs – but the drop ship does launch a mini APC, and there are certainly possibilities there.
The space jockey doesn’t seem to have an exploding stomach. Interchangeable chestplates, maybe?
