If you play on a standard console, it is still the best co-op action RPG available on the system. Whether you’re popping it open for 10 minutes or a 3-hour couch co-op session, the Eternal Collection is essential.

Step-by-Step Installation

Step 1: Acquire the NSP

• Source a clean, unmodified Diablo 3 Eternal Collection NSP (Base game). Often labeled with a title ID (e.g., 01001B300B9BE000).
• Ensure you also get the latest update (as of this writing, version 2.7.7 or higher, which includes the Altar of Rites seasonal theme).

Step 2: Transfer to SD Card or USB Install

• Method A (USB Install – Faster): Connect your Switch to a PC via USB-C. Open DBI on the Switch, choose "Run MTP responder." Copy the NSP and update files to the "MicroSD Install" folder.
• Method B (SD Card): Copy NSP files to the install folder on your SD card.

Step 3: Install via Tinfoil/DBI

• Launch Tinfoil. Navigate to "File Browser."
• Locate your NSP. Click "Install."
• Choose "Install to SD" (recommended, as Diablo runs better from SD than NAND).

Step 4: Boot the Game

• Return to the Switch home menu. The Diablo 3 icon will appear.
• Launch. The first boot may take 30+ seconds to unpack assets.

Step 5: (Optional) Install Update and DLC Prerequisites

• The Eternal Collection NSP usually includes the Necromancer DLC on-disk. However, a separate NSP update file is required for seasonal play. Install updates the same way (always install base, then update).
