Pineapplestein is a mod for registered Wolfenstein, made by Kody 'Jo' Dagley in collaboration with Daniel Mckone and Evan 'Neo' Newton.
A fun-type mod that sees the player take on these odd-looking yet tasty fruits with a vengeance, it features many changed actors (all but the mutant are now pineapples) and 60 levels, which were all generated with the Creator tool.
A sequel was made later the same year called Pineapplestein 2.
No coding changes are featured, and it is thus playable in SDL.
