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.
No coding changes are featured, and it is thus playable in SDL.
