I absolutely love the base game but even I will admit that this DLC doesn't provide much incentive to complete its difficult challenges.

Artic Cruise is also probably my least favorite level when compared to the others. Not based on its design, the cruise ship is really fun to explore! But there are only 3 chapters and only 1 of them actually capitalizes on this exploration.

But even with that the platforming is still superb so you won't feel that your time is wasted by giving this a go.
