|Alternate Musou Attack|
When your Musou meter is full, press Circle to begin the attack. Then, release Circle and press Square rapidly. Your character will stop their regular Musou attack and hit the enemies with stronger versions of their charge attacks. This is especially useful with characters such as Nobunaga, that have erratic Musou attacks that only work against large groups.
While playing a game, hold Start + Select.
At the character select screen, a green cursor around your character indicates that specific character is a "lucky" character. These characters can receive their fifth and sixth level weapons one difficulty below the supposed setting.
Note: Every time the game is turned off and restarted, the cursor will randomly change to another character.
Play the Battle Of Komaki-Nagakute with Honda Tadakatsu. Win all the missions, then defeat the supply team when it appears.
Play any versus mode option at least 35 times.
