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.
