Ahoy, mateys! 🏴‍☠️

There’s a reason Assassin’s Creed IV: Black Flag is still mentioned in the same breath as modern pirate games like Sea of Thieves. It’s not just an Assassin’s Creed game; it’s the best pirate simulator ever made, wrapped in a hoodie and hidden blades.

And now, on the Nintendo Switch, the NSP + DLC version is making waves again. Whether you’re a veteran privateer or a new Switch owner, here’s why you need to grab this release.

Released in 2019 as part of The Rebel Collection (which bundles Black Flag and Rogue), the Switch version of AC IV is a masterclass in optimization. But for those seeking the NSP—the digital package file used for installed titles—it’s important to understand what you’re getting.

Verdict: It’s not 4K, but it’s a miracle on hybrid hardware. The NSP installs cleanly on both internal storage and microSD.

When the game launched on the eShop, it wasn't just a bare-bones port. It was released as part of a "Legacy Bundle" and later as a standalone title branded effectively as the "Definitive Version" for the hybrid console.

However, the conversation among the hardcore community often revolves around the NSP file itself.

While Black Flag isn’t a new game, the “new” in our title refers to two things:

Installing NSP files outside official eShop purchases typically requires a modified Switch and can violate terms of service and local laws. This post does not endorse piracy. Always use official channels (Nintendo eShop or physical cartridges) to obtain games and DLC.

Note: Specific DLC availability depends on the exact NSP package or eShop listing; versions may bundle everything or offer items separately.
