The Phantom Pain. I really like the meaning behind it and how it's relating to MGSV. It just sets an entirely fresh and darker tone from the rest of the series.

Guns of the Patriots. No one does subtitles better than Kojima.
I agree. It was a tough choice for me between 2 and 4's subtitles. Gotta love the Boston Tea Party implications of 2 that really highlights the subtitle.
Metal Gear Ray = British Tea
The real life Sons of Liberty are the ones who dumped the tea in the pre revolution days. I know the Sons of Liberty had a different in game meaning, but Otacon and Snake's actions could be an allegory for the actual historic events.
