i translated the greek and this is what it said
Maybe some collectors who have the figures of the Hunters' series of Alien VS Predator McFarlane Toys have noticed that their bases are some slots to put some accessories but which never existed. These are the dioramas of the Scar and Celtic Predator, and the base of the Elder Predator. For some reasons that are never formally announced McFarlane Toys has decided not to include in the packaging of the figures as originally presented.
The frustration of many collectors was high, so the team FiguresWorld managed to find and secure some bases and dioramas for Greek collectors who want to complete their collection. All bases are designed to fit perfectly in all figures. It is made from resin and painted by very talented and experienced modelers!
Do not miss the unique opportunity to complete your collection!
