IAmSinistar: I would love for the game to show up here, ideally with the Mountains Of Madness extension included.
Ixamyakxim: Ooooh even includes an existing extension for one of my favorites!
Yes indeed!
At the Mountains of Madness is one of my most favourite HPL works, and the DLC is brutal fun. Old Ones, Shoggoths, giant blind penguins, and perhaps worst of all, falling icicles that you have to constantly be vigilant for.
It's possible to avoid some of the permadeath in the game by carrying the right artifacts, but even then you are forced into a dilemma, because there are certain items you need to carry to unlock the true ending, and you can't do both. I've completed the game but not with the true artifacts, so I'm going through again trying that path now.
The MoM DLC has a different success path - once you achieve the goal, you have to make your way back out again. And you must do so while being pursued by a relentless black cloud of evil. It was nerve-wracking as hell to finish that one.
