Fred vs. Napoleon is one of two Memory Vaults found in Waterloo World in Psychonauts.
After Crispin won 27 rounds of Waterloo-O in a row...
...a humiliated Fred got up, having lost a simple game of war to a feeble-minded invalid.
Fred looked in the bathroom mirror, and in his mind's eye, he saw the genetic memory of his ancestor, General Napoleon Bonaparte.
And then, in Fred's mind, Napoleon suddenly seized control of him.
Napoleon would remain in control until his descendant learned the love of victory.
