Every so often I stumble upon, or revisit a game which is just the equivalent of crack in terms of highly enjoyable and pulsating combat. These games just have that extra something which really stands out and where the combat shines mechanically and even visually. Off the top of my head, I'd say 3 games which really stand out are:-
Metal Gear Rising - fast paced, responsive, smooth and incredibly satisfying melee-based combat.
F.E.A.R - inspired by Max Payne's bullet time feature but with additional immersion thanks to the first person perspective.
Max Payne 3 - bullet time never gets old plus the attention to detail and environmental effects look spectacular.
There's probably loads more that I've forgotten about but what are your standout games that just have that little bit more in terms of the combat?
