How do you purchase Left for Dead 1/2 digitally?

They were delisted so it's no longer possible to purchase them digitally. The only other way would be to find them on disc.

I see, thank you for clearing that up.

The links to the Left 4 Dead 1 DLC you just posted said "Already Purchased". The links for the Left 4 Dead 2 DLC asked me to buy them again. We've gone full circle back to the problem of I used to own the Left 4 Dead 2 DLC but it's asking me to buy them
again.

But I do appreciate you clarifying the DLC's contents.

Try checking here:

Left 4 Dead 2- https://marketplace.xbox.com/Produc...-9115-d802454108d4?DownloadType=Game#LiveZone

If you can't get them there, that usually means the games are not available for purchase digitally in your region.

good afternoon

unfortunately the game Left 4 Dead 2 has been removed from Microsoft's digital stores some time ago, and cannot be purchased this way, only on physical media.
