How do you get Ma Chaos level 11 weapon in Dynasty Warriors 4 Extreme Legends?

Achieve at least 500 KO Count.

Receive Ma Chao is taking the lead message over 5 times.

Finish the stage achieving twice the KO Count as the ally general in the

second place.

499 KO Count is an "A" rank.

500 KO Count and above can be an "S" rank.

But just achieving 500 KO Count won't unlock the weapon.

Immediately after game start, head to the bottom fort and fight in front of

the bottom enemy entry point, just far away enough from the entry point

captain that you don't attract him to you so that you won't have to fight

and defeat him. Enemy soldiers will come to you by themselves. Keep fighting

here and achieve twice as many KOs as the ally general in the second place.

Be mindful of the KO Count reports of your fellow ally Five Tiger

Generals.

The 1st time I tried to unlock this weapon: Ma Chao = 683 KO Count.

Zhang Fei = 450 KO Count report.

I didn't unlock the weapon.

The 2nd time:

Ma Chao = 772 KO Count.

Guan Yu = 400 KO Count report.

I didn't unlock the weapon.

The 3rd time:

Ma Chao = 484 KO Count.

Huang Zhong = 250 KO Count report.

I didn't unlock the weapon.

The 4th time:

Ma Chao = 561 KO Count.

Huang Zhong = 250 KO Count report.

I unlocked the weapon, but didn't save because I did not understand fully

and wanted to do some more testing.

Then after some more tests, when I was almost certain of the conclusion that

getting twice the KO Count as the ally general in the second place will

unlock the weapon, this result broke the rule:

Ma Chao = 928 KO Count.

Guan Yu = 450 KO Count report (2 seconds before the end of stage).

I did not unlock the weapon.

So I did some re-thinking, and started taking notice of the who's taking the

lead messages. So I started counting.

Test 1:

Ma Chao in the lead = 8 times (734 KO Count).

Zhao Yun in the lead = 0 times (250 KO Count).

Guan Yu in the lead = 2 times (200 KO Count).

I got the weapon.

Test 2:

Ma Chao in the lead = 6 times (585 KO Count).

Guan Yu in the lead = 1 time (250 KO Count).

I got the weapon.

Test 3:

Zhang Fei won.

Test 4:

Ma Chao in the lead = 4 times (775 KO Count).

Guan Yu in the lead = 1 time (300 KO Count).

I did not get the weapon.

Test 5:

Ma Chao in the lead = 5 times (585 KO Count).

Zhao Yun in the lead = 1 time (250 KO Count).

I got the weapon.

Taking all the above test results into consideration, I arrived at my

conclusion. Do this on Expert Mode
