Raise a weapon type to the maximum levels, then defeat 500 enemies to unlock the level 4 weapon type for that character. Note: Each type of weapon is only unlocked based on your own weapon. Hence, a sword unlocks level 4 swords, etc. Alternately, play Empire mode on any difficulty setting. Defeat the main Boss of a stage in less than four minutes to get a level 4 weapon at the end of the stage.
Play the level where you rescue the Emperor from Li Jue, Lubu, etc. Go to where Li Jue is located and kill him. Near him should be a gate where men constantly pour out. Have your men fight the Gate Captain while you stand directly in front of the gate (where you cannot walk towards it any more). Do not kill the Gate Guard as this will stop the reinforcements. Just remain there and attack, killing all the men you come in intact with. Once you get 1,000 K.O.s, complete the level.
Defeat 1,000 enemies in any stage on any difficulty setting to unlock the ability to use six items for that officer. For easier results, use two Extend Time strategy cards.
To get the Red Hare Harness, you need money and the Development and Production assignment cards. The cities that are able to develop the Red Hare Harness are Nanman (in the Gathering Of Heroes campaign) and Luo Yang (in all other campaigns). You must use the Development assignment card (under the "Equipment" category) on that city three times. After that, you must then use the Production assignment card on Luo Yang. This will produce one Red Hare Harness. If you want another one, just use the Production assignment card on it again.
Get the northwest most land (should be owned by Ma Teng), then develop it until you cannot do so anymore. After you are done developing, go to "Assign" and do "Western Trade". Repeat this until you get the Shadow Horse.
Put Zhuge Liang and Yue Ying together in the same province to unlock the Juggernaut and Wood Ox cards.
To get better assignment cards, you must play Empire mode on the Hard or Chaos difficulty setting. Not a lot of good assignment cards will be unlocked on the Novice or Easy difficulty setting.
Always save your game before choosing policies or going into battle. If you do not get desired results, load your saved game and try again. By doing this, you can get better results with policies and never lose a battle.
Defeat 1,000 enemies in any stage and difficult setting to unlock the 1,000 KO Medal.
When invading an enemy territory, start with a Saddle, Orb, Peacock Amulet, Tiger Amulet, Tortise Amulet, Dragon Amulet, and Serpent or Naga Earrings if available. Go directly to the enemy's main camp and kill as many of them as possible. It is possible to get 3,000 KOs per stage. When you have the earrings equipped you can get max stats quickly because you will get +2 attack and defense for every 100 kills.
