Scenario A: You own Assassin's Creed 3 Remastered (2019)

If you purchased the Remaster (often included free with the Season Pass of Assassin's Creed Odyssey or bought separately), the DLC is almost certainly included automatically.

1. Open your platform launcher (Ubisoft Connect, Steam, or Epic Games Store).
2. Navigate to your Game Library.
3. Select Assassin's Creed 3 Remastered.
4. Go to DLC or Owned DLC. You should see "Benedict Arnold Missions" and "Tyranny of King Washington" listed.
5. Ensure the boxes are checked to install them. They are often installed by default.

For Users Who Own Assassin's Creed III on PC:

1. Ensure You Have the Latest Version of Uplay (Ubisoft Connect):

   • First, make sure you have the latest version of Ubisoft Connect (formerly Uplay) installed on your PC. You can download it from the official Ubisoft website.

2. Launch Ubisoft Connect:

   • Open Ubisoft Connect and log in with your Ubisoft account credentials.

3. Navigate to Your Game Library:

   • In Ubisoft Connect, go to the "Games" section, and find Assassin's Creed III in your library.

4. Check for DLCs:

   • Click on Assassin's Creed III, and then look for the "DLC" or "Add-ons" section. This might be directly visible or under a menu like "Properties" or "Details."

5. Download and Install DLCs:

   • You will see a list of available DLCs for Assassin's Creed III. Click on the DLC you wish to download, and then select "Download" or "Install." The DLCs will start downloading and installing automatically through Ubisoft Connect.

Error #3: "Download Failed" inside the game menu

• Cause: The in-game store is deprecated.
• Fix: You cannot download DLC from inside the game anymore. You must exit, download via your storefront (Steam/Ubi), and re-launch.

Part 3: Step-by-Step Installation Guide (Original PC Version)

You have the files. Now, how do you make the DLC appear in-game? Many PC users download the pack, install it, but the game still says "Purchase Episode 1."

Follow these steps precisely:

1. Download the DLC installer. Do not just drop folders into the game directory. Use the .exe installer from Ubisoft Connect.
2. Run the installer as Administrator. Right-click the installer > "Run as administrator." AC3 writes to the Program Files folder, which is locked by Windows.
3. Install in order: Base Game > Patch 1.03 (critical) > Tyranny Ep 1 > Tyranny Ep 2 > Tyranny Ep 3 > Hidden Secrets Pack.
4. Verify the files. Go to:
   C:\Program Files (x86)\Ubisoft\Ubisoft Game Launcher\games\Assassin's Creed 3\
   Look for a folder named DLC_18 (Tyranny) and DLC_26 (Hidden Secrets). If they are missing, the install failed.
5. Launch via Ubisoft Connect offline mode. Uplay’s cloud sync sometimes disables DLC. Go offline, launch the game, and check the "Bonuses" menu.

For Steam Users:

• Right-click AC3 in your library > Properties > DLC.
• Ensure all checkboxes are ticked.
• Force a file verification: Properties > Local Files > Verify integrity of game files. Steam will re-download missing DLC components.

Scenario B: You own the Original Assassin's Creed 3 (2012)

If you are playing the classic version, the process can be trickier as the original storefront infrastructure has aged.

1. Ubisoft Connect (formerly Uplay): The original game is primarily hosted here. If you own a "Deluxe Edition" or a "Season Pass," the DLC should appear under the "Owned DLC" tab in the game properties. Click "Install" next to each pack.
2. Steam: If you own the original Steam version, you may notice the Steam Store page for the original game has been delisted in favor of the Remaster.
   • If the DLC is not automatically added to your library, check your Steam Inventory or the "CD Keys" section of the game properties. You may need to redeem these keys inside the Ubisoft Connect launcher to authorize the download.

Part 1: What’s Inside the Assassin’s Creed 3 DLC Pack?

Before you hit that download button, you need to know exactly what you are getting. The "DLC Pack" for AC3 is not just one file; it is a collection of content packs. Here is the complete breakdown:

Option A: The Official Storefronts (Recommended)

• Steam: Search for Assassin’s Creed 3 Deluxe Edition. The DLC pack is listed as "Season Pass." Buy it, and Steam auto-installs the files into the AC3SP.exe directory.
• Ubisoft Connect (formerly Uplay): Often the cheapest. Look for the "DLC Bundle." Ubisoft frequently gives the Tyranny of King Washington away for free during AC anniversaries.
• Epic Games Store: Only applies to the Remastered version. The "DLC Pack" here is just a single 4K texture patch.
