Now this looks cool. If you know anything about the battle of Thermopylae you'll wanna at least check out the trailer. If you are not from the Naval Academy (and thereby havent read one of my favorite books, Gates of Fire) the battle is basically how an tiny band Greeks held back an army of a million Persians.

Basically the elite (in every sense of the word) Spartans had 300 men combined with small contingents of other Greeks added up to a few thousand men attempted to guard Greece from Xerxes army of a million men (some estimates hold at only 100,00 and some as many as a few million . . . regardless they had almost no hope of victory) by stopping them at a pass-the Hot Gates-where only twenty men abreast could pass (thus neutralizing the massive Persian numerical superiority.

I won't give away any more, you can wikipedia it if you so desire, but I'll just say that I am looking forward to this one.
