This may seem long,but it's easy
First,go to free mode.choose the character of your choice and go to the the level with the
natives.it has native looking houses and a long name.set the difficulty on "easy".once
done,head towards the plain areas on the map.there should be small groups of enemies
there.once done,head to the glowing red dot where the leader is.do not kill him.deafeat
his minions and take any elephant(optinal).go northwest.there should be some elephants and
minions.kill the minions and knock the guys off there elephants.go farther in the camp,you
should see your allies struggling with a group of enemies.kill them,then head to the
leader again.kill any minions on the way.you can try to knok him off his elephant with an
elephant of your own(triangle)or you can try to knock him off with your own weapon.once
hes off even more enemies will come to his aid.quikly kill them(optinal) then kill the
general.                                                           this will allow 200-650
