Summary: Thought i would throw in my two cents since i just finished this game. All i have to say is that it is quite an adventure. The pacing is good, and the atmosphere is amazing. The game has a little bit of survival horror in it and is mostly an FPS. The game is great at pulling you into the world that it offers. Is it linear yes but the story more than makes up for it. I have played all the fallout's, and many other post-apocalyptic games and i feel this one is special.
Summary: You buy this DLC for one mission only--- Kshatriya. You can call it a throwback to the original STALKER series. Go out to the world, gather stuff and sell them. You make money, upgrade your gear, suit, ammo and others. It's almost like an non-linear RPG fps. It's quite long. But since I enjoyed it so much, it's never long enough. Damn fine piece of work this is!
Summary: Really great and immersive story. Wish I had seen the reviews telling me to play it in Hard mode for the best experience. Also wish the developer had saw fit to include Ranger mode rather than making it a $5 add on. If you liked Metro 2033, or if you like an atmospheric-type shoot 'em up (a la Bioshock) give this one a try.
