This is a tactical-lite mode. You command the Survey Corps to retake walled cities on an overworld map. It adds 50+ hours of gameplay, a loot system, and a base-building mechanic.
Is it worth the effort to track down the specific update and DLC NSPs? attack on titan 2 switch nsp update dlc
Yes, if: You already own the base physical cartridge and want to legally back it up with the Final Battle DLC to avoid swapping carts. This is a tactical-lite mode
No, if: You are starting from scratch. The scene is filled with malware-ridden Attack on Titan 2 - Final Battle [v0].xci files missing the 1.0.13 update. You are better off using a single-source NSP for the Complete Edition. Method B is rarely stable
This is where the keyword hierarchy matters. If you search for "attack on titan 2 switch nsp update dlc", you are likely looking for the Final Battle upgrade. However, note that the Final Battle content is so large (over 6 GB with the high-res textures) that most scene release groups treat it as a separate base game NSP rather than a simple DLC.
Method B is rarely stable. The Switch’s memory management often crashes when injecting the Final Battle data as an add-on over the vanilla NSP. Pro tip: Just get the Final Battle NSP directly.
