Okay if you go and get the red hare harness by: Go to battle of Chang Shang as Yuan Shao's forces, and defeat Liu Bei, Guan Yu, and Zhange Fei All in no more then sixty seconds of each other. (I usually get them all almost dead, and then kill them in this order. Zhange Fei, Guan Yu, and Liu Bei, because if Liu Bei dies, they all run away. Note player 1 Has to kill all three.) After that a valuable item will apear, grab it. The dificoulty doesn't matter.
Then in Liang Province Kill enough people that your allies can kill the only remaining officer outside the gate, and then wait at the base on the bottem left of the map for Your allies to kill the remaining officer, and then Dong Zhou appears. Shortly after that he calls in his reinforcements Hu Zhen and Zhang Ji. They appear in the bases at the top right, and bottem left, where you should be waiting. Then use that red hare you got in then last level to race across the map, and kill the other one. Be warned you only have one minute to kill them after they arrive. Then a valuable item appears go grab it. Then In the battle of Tong Gate on hard mode use the red hare to start the level and run up to Cao Cao, and snock him off his horse before he crosses any River at all. Then a valuable item will apear grab it. It will be Ma Chao's last weapon!
Not you must be playing on hard mode when you do that last one.

Then go and train Ma Chao to be really good. (60,000 points.) Then give him the Horned helm, attack plus, Defence plus, Musou max plus, and Life max plus. Tehn if you equip the serpent earings that you get by...

Serpent Earrings;
Attack up +2 every 100 kills.
Battle of He Fei
Wu Army
Your end goal is to defeat all Wei reinforcements, finishing with Xiahou Dun,
in one minute. There's quite a lot you have to do to get to this point. When
the stage begins, proceed westward and defeat Pang De and Cao Zhang. Head
southwards and through the enemy base; this will trigger Xu Huang as a
reinforcement. Go through and defeat him. Now return to the center area and go
southwards. Zhang Liao should show up and surprise attack Sun Quan. Defeat him.
Head up to the north area and attack the enemy base there; this will prompt Yu
Jin to show up as a replacement. Defeat him. Hang out in the north for awhile,
and defeat Zhang Liao when he shows up as a reinforcement for the second time.
Now head to the northeast corner's gate and sit tight. Xiahou Dun will show up
eventually and charge southwards at Sun Quan. He'll even ignore you so make
sure you're ready to knock him off his horse and take him down. Once you do,
the Precious Item box will appear in the central island.
Information Givin to me from the guy who write this guid: http://www.gamefaqs.com/console/xbox/file/927523/43989 (It has a lot of stuff you might be interested in, like how to get the rest of the items. How cool is that!)

Then you can get rid of one of your items, and go to a really easy level, and stand by a gate, and kill people to get max strength. And that will max out your strength, and then go find some place to get good, everything else, and then with those items (Storm harness, peacock amulate, Dragon amulate, attack plus thing, Defence plus thing, Horned helm.) You are invincable! I defeated a five circle dificoulty level in chaos mode, This is why Ma Chao, is the way to go!
