Yesterday I was playing it on medium lol, and suprisingly that was hard, a bit...
So I started all over again on easy, and so far, so good.
Man it was all paradise until later on in the game it turns into night-time, and killing Trigens in underground bases. Starting to get scary here... lol.
Man I hate those elite mercs lol. One part involved me trying to get past them in a room, where I seriously needed CryVision enabled - thing is, when I chucked it on, it lagged me out, so I had to stick to my flashlight.
I think I'm on the chapter "Cooler" now, which shouldn't be too far away from the end. I'm also being lazy and using the walkthrough every now and then, hehe.
Graphics are definitely good for its time. I'm playing it on all low settings (except texture detail which is on medium). Seen screenies of it on very high, and it looks somewhat similiar to Crysis.
Hope it goes to day time again in the game. The night is getting scary...
