Penumbra and At the Mountains of Madness

[The Rock Worm]

At times I've wanted to make "At the Mountains of Madness" as an Amnesia Custom Story. The snow Penumbra has, but the textures (not to mention the monsters) would have to be a custom job.

At the Mountains of Madness-CS would be awesome! Though I don't know how well HPL2 would handle a large outdoor map... Source-mod anyone?

Not sure myself, haven't tried making a large outdoor area, let alone one as big as the one described in the book!
