The changes were incredibly apparent right from the start, when the developers guiding the demo sneaked up behind a guard and took him out with the kind of close-quarters combat neck-snap you might expect to see in every bit of pop culture ever (but not the original Goldeneye). Taking out two more guards with headshots ensured that the alarm wouldn't be raised and the game could remain a Splinter Cell-style stealth experience for at least a while longer.
