In my local Compustore in galway somebody had loaded the game on a test PC Athlon 1.3 64 mbgfx 256mbRAM. So I tried it out. It's amazing! the interface is simple and the default keys are well spaced I didn't need to change them. The graphics were beaitiful and the enemy AI was very good even on the easiest level. For example I came across a guard who when he first saw me started shooting then hid behind a pillar to reload his gun and then ran sideways while shooting at me behind a desk. Needless to say he didn't make cover quite in time
I got outside on top of the building and the scene was breath-taking it the horizon looked very realistic and the castle itself looked very complex but I did notice a couple of slow frame rates when a couple of guards came in front of me and started shooting as I was looking at the castle. But not too bad seeing as I had the graphics all the way up. That's when I died and was late for meeting someone in town
The storyline from what I saw looks very promising and the player abilities ( don't have a key try kicking down the door ) were extensive.
Overall very good if you have a good enough PC then buy it.
