So it's been a while since I've talked about DLC. Well, since the newest Batman: Arkham Origins DLC, Cold Cold Heart, just came out, it's only fitting that I talk about that, now isn't it?
This story takes place a week after the events of the main story of Arkham Origins. Bruce Wayne is holding some awards ceremony at his mansion, when suddenly some goons burst in with Mr. Freeze, demanding the guest of honor. After Bruce takes out some thugs and suits up, he goes after Freeze, but soon discovers he'll need a different suit, and gets a bulkier Extreme Temperatures suit. With this suit, maybe he stands a chance against Freeze...
Really, you only get most of the bottom half of the map to explore, since the bridge is closed. All around, there are also frozen victims you can free, Anarky followers causing riots, and Anarky symbols. Collecting all those shouldn't take too long. The new Batsuit also comes with upgraded Batarangs, which can be charged with heat.
Overall, this DLC is pretty short. You can complete it in a couple hours, there's not much to do after you beat it, but it is good for what it is. I don't know if I'd say it was worth the wait, but I can at least say it's good.
HBM, signing out.
