Thank you for your comments! Rating something is a very subjective thing. Playing this in say 2001 I'd probably give it at least a 9 as there was nothing quite like it then. But then how can we distinguish between things? My rating wont damage this classical masterpiece.
Thank you for your review!
Not trying to argue with you in any way, but there is actually a fair explanation of why several guards are no-KO.
The reason is that normal guards have their necks exposed, while no-KO guards have their necks covered with metal helmet.
During gameplay, we cannot see that in simplified animations, but Garrett is supposed to knock them out with the neck or lower head hit, and not hitting directly onto the metal helmet.
Thought this could be a nice fun fac...
