Ps4 – Will uninstalling a game on the PS4 remove it forever

You might not like this answer, but if you didn't have a PSN account in April, you won't qualify for the freebies. If you have only just purchased your PS3, then this will be the case, and you should just keep the disc.

On the other hand, if you do qualify for the freebies, then yes--the games should share the data. I base this on the example of Dead Space: Extraction. I had the game on PSN before I purchased Dead Space 2 Collectors Edition, which came with a copy of the game on the disc. I installed Extraction from the disc, and then launched it from the disc--it shared the data from my previous PSN version of the game.

Of course, it could just be a special case with Extraction, but that would be quite unexpected.

You did not get ripped of. You got what you paid for.

From what I could tell, I found that in the bundled items it displays:

• PlayStation®4 System (Glacier White)
• DualShock®4 Wireless Controller (Glacier White)
• Destiny Video Game (Physical Disc)
• 30-Day PlayStation Plus Trial
• HDMI Cable
• Power Cable
• Wired Mono Headset
• USB Charging Cable

I could not find any mention of the "Digital Guardian Edition" so they are not entitled to give you the additional expansion pack.

You may have received the disc for the expansion pack version, and the armory code (although expired), you did not buy the Digital Guardian Edition so your not entitled to anything extra.
