The Worry of Newport is a two part Horror/Mystery built upon Crysis 1. It is an interactive narrative and story built upon the first person perspective around immersion, story, and atmosphere.

Before I say anything, the Crysis engine itself causes most of this mod's flaws. Some advice before playing: Take it slow and don't try to break things. Much like the genre, the mod is quite fragile.
Despite being rather user-unfriendly, it is a very good mod. Starting with the story (also the SPOILERS!), I predicted the character of Gray right from the winter flashback. Many things factored into this, and it really spoiled the game for me.
After some discussion, I now realise this is a Lovecraftian story with the past/future being the main focus. In this regard, it has been very well done. Lovecraftian storytelling is hard to pick up on and follow unprepared, and you really have to know it is coming.
This is quite a linear mod, and with the small team and short development time (already quite amazing) it isn't unexpected. This mod is still a major step above most horror games, and the masters - Frictional Games - have had a long time to perfect making a game feel more non-linear than it is. As they have stated in one of their blog posts, the player really has to scare themselves, or at least think they did...
The overall atmosphere and visuals are great. With a few odd or unnatural looking things here and there, it's not too intrusive. The music is excellent, but lack of ambient sound or music, the silence in some parts is distracting. At worst, it further spoils the monster house part after the narrator has given it away already. That part of the mod suffers from its linearity, but that is not to say it is ruined. The parts with the camera on rails are also quite disconnecting.
There are a few bugs or weird things here and there. The intro went out of sync slightly which happens to the richest (Portal2), and the arm coming up at the end was kinda weird.
Now that I've hit the character limit: Definately worth playing. If this was longer and more polished, I could even see it being on steam.
