Crowning Moments of Awesome

[The Artist Formerly Known as Hawk]

Pretty much any opening level/boss fight in the God of War series, especially the opening minutes of GoW3 and the battle with Cronus.

Metal Gear Solid 4 - Rex vs Ray fight

Arkham Asylum - When you get the chance to go Predator on a room full of mooks and get to hear them freak out as they find more and more bodies of their buddies and never see you.

Fallout 3 - Liberty Prime

Freedom Fighters - storming the Soviet news channel

Prototype - the first time I was able to do the dive bomb attack into Times Square and hitting a packed intersection

Okami - the boss fights especially the fight against the clockwork owls

Shadow of the Colossus - all of the colossi really. the sword-swinger was awesome, but the two fliers and the final colossus were my favorites

To avoid sounding repetitive with my Mass Effect inserts, I will simply second this because it's a crowning moment of awesome that doesn't involve Bioware somehow.

Left 4 Dead 2 - Every time I play. Edit: Okay, the one that comes to mind was while playing Sugar Mill level on Expert Realism. Naturally, we'd already died numerous times. We're heading into the beginning of the witch-infested areas when we get the inevitable tank sound. My buddy playing Coach throws a pipe bomb over the entire warehouse and startles a witch. Now we have an Expert Realism tank and witch chasing us around. Coach ended up getting hit by a rock and incapped, but as the Witch ran up to kill him instantly, the tank threw another rock and killed the witch. Tanks in Expert Realism do over a thousand damage! The tank eventually fell and Coach was saved, happy day!

But it was Expert Realism so we died like 10 minutes later.
