Game has a nice flow to it. A good single player experience to get lost in for a little while, if you can find it for $10-$15 I would say jump on it. I got it on sale bundled with Last Light for like $7 a piece.
Its gun play isn't bad compared to even more modern games. But we are getting to be a bit spoiled there.
The graphics are pretty good, it runs decent enough, but prolly not for low-end rigs.
The story is pretty good. The weapons are decent enough, though I feel could have had a better selection. The enemies are kinda cool, the monsters are alright.
The thing that really shines in this game is the atmosphere. The use of setting, music, mood. They did a good job in that department. I really liked traversing in this game. It doesn't hold your hand to tell you where to go all the time, and there is a decent amount of hidden goodies all over the place. I find it refreshing that it doesn't have some neon blinking arrow pointing at the objective or where you need to go all the time. (or some alternative of that most games now-a-days have in abundance)
There isn't a ton of repetition in level design, but you can see it every now and then. I think there are moral moments in the game that you choose to do something, or not, but I am not sure what it really effects. Unless the game has multiple endings. Which I am not sure if it does.
The music is pretty good to. I have had my girlfriend, and my best friend both tell me that they like hearing the music coming out of my room when I play this game. The game does some things just right. Kinda like "Singularity" did. It isn't the best, but its atleast worth giving a shot.
I played it on hard difficulty, and that is what I would recommend as well. It's pretty challenging, but not ridiculous. Ammo can become scarce if you don't search for it, and conserve. I was running into Air issues for my gasmask (I like to explore) but I made it through the game relatively well considering.
One thing that I think this game could use that it had no shred of is boss fights. A game like this could have 3, maybe 4 mini bosses, and 1 final boss. No such thing in this game.
I would recommend having some what of a decent rig if you decide to play it. The length isn't all that long, but it isn't all that short either, its a decent middle length, it could of went longer if it included the boss fights that I mentioned above.
I will be playing the second game Last Light. I hear it was good too.
Some complaints on the game is It is sometimes hard to make out what the other characters in the game are saying. Mainly when you, and they are wearing gas masks, plus the accents. Which I have to point out that you can clearly hear that the accents for some of the people in the game were horrible to the point of being kinda funny. Namely the Nazi/germans. That was funny.
Another complaint is the nightvision goggles in the game aren't calibrated enough, most of the dark places have a few lights in them that make the NVGs almost useless. (they could have adjusted the filters better on it so it doesn't flare as bad constantly) The Night Vision Scope (IR scope as they call it) doesn't suffer from this issue.
It also crashes kinda easily. There a few areas where picking up a set of Air tanks for gas masks, and medipack off of a table in the later half of the game crashed the game for me every time I tried it.
