Finished the Cold, Cold Heart storyline DLC for Batman: Arkham Origins. Overall it was alright, to be honest it was a lot better than Harley Quinn's Revenge back on Batman: Arkham City. My thoughts are below tagged in spoilers.
SPOILERS:
The storyline was alright and while the origins of Mr. Freeze were kinda told in a lazy fashion, it was still entertaining. All of Batman's skills and abilities are unlocked as soon as you get the bat suit, so you don't need to worry about leveling up or anything like that.
When Batman acquires the "EX Environment Suit" (as seen in the trailers) it really doesn't add anything new to the game. Sure, it looks like a sort of Batman/Iron Man suit, but it doesn't add anything new. The Shock Gloves now become Thermal Gloves, the Batarangs become Thermal Batarangs etc. Nothing new. Having this suit at least lets you bypass areas blocked off by ice or extreme cold, so I guess that's something at least.
The final fight with Mr. Freeze is very similar to that of the fight in Batman: Arkham City, albeit Freeze has got some goons with him so it's a little tricky. Just like Arkham City, you can't attack Freeze head on and you'll have to resort to stealth take down tactics.
Once you finish Cold, Cold Heart, you'll be able to free roam what little area of Gotham they give you. In Cold, Cold Heart, over half the map is blocked off to you, limiting you to only two zones. Still, once complete you can go looking for a few things to unlock... Anarky gang signs to scan, frozen police officers to unfreeze, Anarky gangs to stop etc. Completing these side missions offers a new skill each, so I suppose I shouldn't have said before "there's no new skills". Problem is, by the time you tackle and finish these side quests, you'll have probably finished the DLC by then, rendering these skills almost useless.
I was disappointed that the DLC doesn't give any new trophies. I was hoping to check out some 3D model trophies of Batman in his EX environment suit as well as Mr. Freeze himself.
END SPOILERS:
I dunno how much this DLC costs because I bought a Season Pass when I first got Batman: Arkham Origins. If I didn't have the Season Pass, I probably still would have bought it. It was an okay DLC to play but really if you haven't finished Arkham Origins yet (e.g. you've stopped playing) or you weren't fond of Arkham Origins, then I can't really recommend it to you. If you've finished Arkham Origins and you enjoyed the game, I suggest you go check out Cold, Cold Heart.
