in the PS2 version, lu bu cannot be killed unless ur using a
character u have lvled up several times with increased attack and
def.
once u meet him at one of the gates, u can try killing his men but
not him.
linger ard at his area using musou and run if necessary to
survive.
soon, ur commander or someone will tell ya to forgo the
fight.
dun go off and wait till the announcement for the opening of north
east gate(can see by the rippling circle that its north east) pops
up. the enemy gate captain should be wiped out by ur allies. now
forgo lu bu and run towards the northeast gate.
find dong zhuo from there.
