Had a good session on it last night, really enjoyed it. Actually enjoyed the yellow stealth zones more than the red zones and i normally hate stealthy stuff.
Graphics are great and its silky smooth, as with many games of this type turning off as many HUD options as possible helps greatly with immersion, the minimap especially ruins it with great big icons all over it.
Playing on hardest difficult which feels right, only died once or twice from going rambo
Great pick up for £9, thanks OP!
