Dynasty Warriors 5

All 4th weapons must be completed on Hard or Chaos mode.

Play the Battle of Si Shui Gate with Dong Zhuo's forces. Kill Sun Jian at the very beginning of the battle. The "A valuable item has been found" message will appear shortly after you kill him. Note: You can do this with any officer, but there is a time limit. You do not need to kill Sun Jian's Sub-Officers. This items prevents damage during charge attacks.

Play the Battle of Chi Bi with Cao Cao's forces. Defeat Zhuge Liang when his unit begins to retreat to get the Art of War. This item allows boost items to last longer.

Play the Guan Yu Escape level on any difficulty setting. Kill Zhang Liao immediately, without letting him escape. Keep killing officers until about gate 3. The special item message will appear. The item is at the beginning of the map. You should have a horse to hurry back there before the caravan is destroyed.

While fighting someone difficult, such as a general or the Boss of the stage, set them on fire with a charge attack or equipped item. It will drain their health until they hit the ground. If you set them on fire and continuously juggle them in the air with an attack, the fire will keep diminishing their health.

Play the Battle Of Xia Pi on the hard difficulty setting. Defeat Gao Shun before you get the message that he is guarding the dam. You can get the message that he has begun guarding the dam, but you must defeat him quickly after that. Then, just defeat Zhang Liao. The precious item box will show up outside the castle just outside the south gate. Because defeating Gao Shun makes the castle be flooded, you must to go in the castle from the north gate and go through to the south gate. Then, just attack Lu Bu. You do not need to defeat him; if you do not defeat him fast enough, he will get bored and run, then and his troops will turn on him and capture him, making you win the stage all the same.

Play the Battle Of Wu Zhang Plains on the hard difficulty setting. It is better to do this in Musou Mode than in Free Mode. Wu Zhang Plains is a five-star battle, but in Cao Pi's Musou Mode it is only his fourth stage. Thus, if you do this in Musou Mode the difficulty will be lowered somewhat. First, defeat any three generals (not sub-generals) quickly. The ones that all grouped in the center make good fodder, as except for Wei Yan they are all generic. Once you kill three generals, Zhuge Liang will pass away. Continue fighting normally. At this point it would be a good idea to seal the enemy's supply route over to the east. Soon you will see an event where Jiang Wei lays a group of automatic crossbows on the central platform. Now all you have to do is get up there and break all of them. There will also be juggernauts floating around, not to mention archer towers -- be careful. Once you have destroyed all single automatic crossbows, the precious item box will conveniently appear in the middle of that central platform. Pick it up and finish the stage to earn your fourth weapon.

Play Escape From Chi Bí on the hard difficulty setting. Your task is to defeat all enemy reinforcements quickly. This means that you should be able to defeat the reinforcement before Cao Cao's own reinforcement says something along the lines of "Go on first, I'll take care of things here!". You do not need to worry about sub-generals; just get each major general as they show up. After you defeat Guan Ping, immediately go south, as Sun Quan will show up in the southeast. Once you defeat Sun Quan, the precious item box will show up in the little nook between where Zhao Yun and Zhang Fei appeared. Grab the item, then go up and defeat Liu Bei to help Cao Cao escape.
