Game Based On Battle of Thermopylae:
The Battle of Thermopylae was fought between an alliance of Greek city-states, led by King Leonidas of Sparta, and the Persian Empire of Xerxes I over the course of three days, during the second Persian invasion of Greece. It took place simultaneously with the naval battle at Artemisium, in August or September 480 BC, at the narrow coastal pass of Thermopylae ('The Hot Gates').
A Greek force of approximately 7,000 men marched north to block the pass in the summer of 480 BC. The Persian army, alleged by the ancient sources to have numbered over one million but today considered to have been much smaller (various figures are given by scholars ranging between about 100,000 and 300,000), arrived at the pass in late August or early September. Vastly outnumbered, the Greeks held off the Persians for seven days in total (including three of battle), before the rear-guard was annihilated in one of history's most famous last stands.
