Has anyone played this HL2 mod?
It is the one game that has provided the most engrossing and terrifying PLAYER CREATED atmosphere I have ever seen.
Single player games can be creepy and tense with all their scripted events and monster closets, but this game allows for some truly insane mind games and psychological terrorising completely controlled by a player.
Imagine you are slowly making your way through a deserted office building with several squadmates, when suddenly a computer monitor just shatters. One of your squad mates freaks out and starts firing blindly in that direction, injuring you and some other teammates slightly. You proceed, then suddenly hear a scream from behind you and turn around just in time to see a teammate explode into pieces all over the floor.
This time you and your other teammate freak out and start shooting like crazy, but you're shooting at nothing.
You proceed a bit further, only to have the skull of another teammate come flying through the doorway at you. Once you breach the next room, you are greeted with the sight of the bodies of several more teammates hanging from the ceiling, swaying slightly.
Suddenly, the bodies start swaying more violently, first the one furthest from you, then one closer to you, then the one right in front of you, and then you're dead.
All of this can happen in a game of Hidden: Source, but NONE OF IT is scripted, and every detail of that is controlled by a (competent) Hidden player.
I have never had a more tense gaming experience than playing against a good hidden.
The first time you start playing on a large military team, you'll feel nice and safe and cozy in your big mob of burly men with guns, which makes the terror even more real when you slowly realise you're the last one left on your team (there's no kill icons like most source games, so the only way to know someone is dead is to see it happen/hear their scream/find their body).
