Atomprojekt is a mod for registered Wolfenstein, made by Barry Christian. It was released on January 21, 2017.
37 levels are featured, and most if not all are very large. Countless new textures have been added, along with a number of new enemies and weapons. The levels are each broken into different sections, with especially the laboratory levels being particularly atmospheric.
Some levels are also notoriously challenging. As with all other Barry Christian mods, it is heavily rooted in classic Wolfenstein, though given its many features, it holds its own as a unique mod.
