Exactly! It's a playable version of Heart of Ice, with more time to build the story and accentuate the emotions. The way they built in Bruce's preconceptions in order to build up the tragedy of Victor Fries was beautiful.I love this DLC. It's 'Heart of Ice' in video game form with a few extra cool additions and touches to it.
This is an add-on DLC storyline for Batman: Arkham Origins. So first you'll need to buy Arkham Origins either for console or PC.

Then you'll need to purchase the DLC and download it to your machine.
I highly recommend it, as it's a substantial addition to the story, and a well crafted one at that.
