Ok here is my first one:
- The game has a resident evil 1/2/3 survival horror atmosphere.
- The first level is in a train, i remember a snowy cutscene as an intro
- The protagonist is a soldier or special agent of some sorts with a green suit and a kevlar
- The game was 3D with fixed camera angles.
- The first enemies where some guys with gas masks.
- Also that Resident evil feel of "examine" something where everything froozes.
- It was Playstation one game.
Basically... it was really like resident evil but with people and guns...like, Dino crisis kind of game.
Pretty damn sure it's
There's a snow train later in the game. I think you're remembering the demo as that was the snow level. Skip to 1:19:00
