Just played through the demo. Really impressive. Lots of nice details like the swinging animation of cable on the sniper gun. The visuals are really nice.
I didnt think the bots were hard, imho a little too easy, really. The movement was quite realistic, and Im not sure what the other person was complaining about with the gun aim - perfectly fine. Liked it - clean and accurate.
Also the gun controls were mostly pretty good. There were some quirks, but I dont think its anything horrible, gameplay wise, it works well, good fast-paced, high intensity (hence the high damage and such) action. Very classic Far Cry.
Good vibe. Thanks.
