If it's Latin, then it means:
On the day of the heart
cordis = of the heart (genitive singular of cor, heart)
die = on the day (ablative singular of dies, day)
According to http://callofduty.wikia.com/wiki/Cordis_…
"Cordis Die" is the main enemy faction in "Call of Duty: Black Ops II". It is led by Raul Menendez.
Here's a further explanation:
Raul Menendez is a flesh and blood character motivated out of both love and loss. Indeed, I have found those moments where the player is put into the shoes of Menendez - is this ability to see things from the villain's perspective a first for a CoD game? - to be some of the most engaging sequences I have ever experienced in a game. Hope and despair, vengeance and sympathy, indeed, the gamut of human emotional frailty is the beating heart of Black Ops 2, hence the Cordis Die ("Heart Day") theme that penetrates the story in both a tangible and metaphorical fashion (fire as a metaphor also makes a repeated appearance - some interesting subtext there). http://forums.gamesquad.com/entry.php?14…
