The Scorn greenlight trailer.
For reference, I posted this on Bog's ask page but it bears repeating here because holy crap.
This is probably the most disturbing realisation of Giger and others I have ever seen. It honestly made me queazy. And the idea that this is a thing you can actually play and experience yourself is as 'blarg as all splee' has it were.
Apparently they had a kickstarter trailer for this that I had never seen or I had forgotten about and this new trailer is miles ahead.
I've been waiting for this game for a long time.
I didn't even know that until now.
