I should check if the game was originally released on other platforms and then ported to Switch. The original Wolfenstein II launched on PlayStation 4, Xbox One, and PC in 2017, then later came to Switch. So the NSP update might be part of the maintenance for the ported version. Features for the update could include bug fixes, optimization for lower-end hardware (Switch has less power than PS4/Xbox One), texture quality adjustments, or frame rate tweaks.

Final Rating: * 4.5/5 (for performance improvements, but expect minor visual concessions).

Graphics settings: On Switch, the game might run in Dynamic Resolution Scaling or lower to maintain a stable frame rate. The NSP update could optimize resolution scaling or adjust visual elements for better performance.

Multiplayer? No, Wolfenstein II is primarily single-player with some co-op, but most of the multiplayer features were cut after the PC/PS4/Xbox versions. So the NSP update probably doesn't include new multiplayer modes.
