The pack uses the "Simonrim" mod suite (by SimonMagus) to create a cohesive, balanced overhaul of Skyrim's core RPG systems.
Every rock, tree, and blade of grass has been replaced with high-fidelity assets. The forests of Falkreath are dense and claustrophobic, while the tundra of Whiterun feels vast and ancient.
Unlike modlists that "gut" the game for adult content, Masterstroke integrates these features as a "tasteful" and optional layer.
