Start with additional characters.
Start the game with a memory card with a saved game from Dynasty Warriors 2. Some characters unlocked in Dynasty Warriors 2 will be available in your new game.
Play as Lu Bu.
On Hu Loa Gate, get over 1000 KOs and defeat Lu Bu. This can only be done while on the Allied forces.

An easier way to get over 1000 KOs on Hu Lao Gate is play on the easy difficulty setting, then pay attention to the enemy gates. If you see a lot of enemy units pouring out, make sure to put your bodyguards on defense then stay near the gate opening. KO the enemies as they appear. Try not to KO the Gate Captain or no more units will appear. This is especially critical around the three gates in Dong Zhuo's fortress where you can accumulate over 450 KOs.


Art Of War Scroll special item.
Play The Siege Of Hei Fei Castle as the Blue forces. Defeat all generals except Sun Quan and the special item message will appear. Go to the big boat that Sun Quan is on to receive the Art of War Scroll. It doubles the time of the effect of the Defense and Attack times two for thirty seconds and Musou full for ten seconds.


Black Shadow special item.
Play Huang Gai under the hard difficulty setting at the battle of Chi Bi for Allied forces. Follow orders to execute the fire attack against the Wei (Cao Cao's) forces. Defeat Zhang Liao (and possibly some other generals as well) before defeating Cao Cao. A "Special Item" should be found near the place of prayer at the southwestern end of the map. The Shadow Rod is a +44 attack weapon with 6 hits. It also adds +27 Musou Charge, +82 HP Max, +57 Defense, +52 Mounted Attack, and +23 Reach.


Bodyguard Manual special item.
At the Siege Of He Fan Castle level, go to where Xhu Zhu is located. Defeat him on the ridge and the "Special Item Discovered" message will appear. Complete the level and you will have the Bodyguard Manual, which makes your bodyguards stronger.


Buckler special item.
This item prevents you from be overpowered while blocking. Play the He Fie level as the Wu side. Allow Taishi Ci to get killed in the arrow attack, then retreat with Sun Quan to the lower right corner of the level, to the broken bridge. You will jump over the bridge with Sun Quan. About five minutes later, Zhang Liao will attack Sun Quan. Defeat Zhang Liao and he will drop the item. This item is very useful when blocking, especially when fighting against Lu Bu.


Cao Cao's special item.
Play the Yellow Turban level, on the Han side. You must defeat Zhang Bao and Zhang Liang, in that order, without any gates being lost. Once you have done this, a supply team will appear on the northwest enemy entry point and will make its way to the entry point on the top center of the screen. Kill the supply captain to get the Cao Cao's fourth weapon, Wrath Of Heaven. This weapon is well worth the work. His sixth attack has a purple haze around it and will kill anyone on contact except a Boss.


Dian Wei's special item.
Play the Battle At Wan Castle level as Dian Wei under the hard difficulty setting . Defeat general Hu Che Er. A supply captain will appear in the south. Defeat him to get Dian Wei's fourth weapon, which as HP +84, Attack +27, and Musou Charge +28
