You are a captured citizen who wakes up in a pod, stranded in unknown snowy surroundings, just after you were lost from a "combine-dropship-pod-container". You discover a secret underground facility that are infested by headcrab-zombies. Later you find out that your'e not alone in the facility: A mad group of dangerous humans with weapons are inhabiting the facility too. Lost in the snow will include: notes, keys, puzzles and more.
This is a really nice mod. There are a few sections where health was an issue or I was at a lose what to do even with the notes. Overall this mod came as a surprise to me. I never heard of it before it was released. But I am glad I got a chance to play it. Look forward to more mods by this author.
