One of the coolest aspects of this game is how the game world is presented to the player, and each of the large maps that the train will bring you to basically feels like Ravenholm from HL2.. But even bigger. The big terminal from my screen shot above is the perfect example of almost like a high quality FPS map within the larger game world map. You have these massive, sprawling, set pieces for one particular bit of story that are very well designed and have a lot of effort put into it. Instead of just having you run through corridors that attach these things though.. You're moving through a larger game world to get to them, and they are elements of the larger world that make sense. Also, unlike many open world games where you just enter a door and a new level loads, It's all part of the larger well crafted map, with no loading screens. This game really is brilliant, and in a lot of ways it feels like i'm playing what I kind of imagined Half-Life 3 would have been like if it ever would have come out. The attention to detail with everything really is brilliant as well. Even small things like how during night time the flying devil monsters will hang like bats where ever they want, and you can just barely make out their dark silhouette. They aren't just hanging there like static objects either, the animations are just so outstanding.
