Alright, so right now I´m around 2 hours into the game and so far the game has a really nice atmosphere. It manages to visualize Glukhovskys world really well and especially the outdoor levels look amazing.
What annoys me, though, is how much the game feels like a theme park. There are many passages where the player loses control of the character and has to watch his screen passively. Much of the important game mechanics are simply explained to the player instead of letting him figure it out on his own. For example the weakness of the light sensitive spider/scorpion mutants is casually explained and this takes away alot of suspension and possible excitement.
There are areas, of course, where the player can act on his own, but so far it feels like the "passive" parts are in the majority...hopefully that´ll improve, otherwise I´ll be a bit disappointed by the game. I would love to have much more time to explore the different areas instead of being ushered through one corridor after another and being forced to passively watch dialogue...right now I´m being walked from one roller coaster to another with very little space to act on my own.
Otherwise the game is quite nice, especially the variety of guns is great, plus the environment looks "gorgeous", just like a nuked city "should" look like. Now, where did I put my last filter...?
