Run through the corridor right from the fountain. You will leave after a while for the open arena and you will see the gigantic warrior. It is Klompa - giant whom you have to defeat in order to be able to continue the course. Don't try to attack calves of the boss (you won't get higher anyway), because bar of his life (at the bottom of the screen) neither will stir. Instead of an open struggle localize bums on arena's walls: bars, relieves, platforms etc. You have to be in the persistent movement so that the huge Klomps'a sword won't reach you.
Speed to the stairs, located in one part of the arena. You got relief above you, run vertically over the wall and stick the dagger into it. Take off to the right and snag on adjacent relief with the blade, then jump again from it to the platform on the right. Climb up the stirs and run vertically over the wall, sticking the dagger into the bas-relief above. Jump to the left from this position, you reached the platform at top level of the arena. Climb the catwalk straight ahead of boss and press the speed kill mode.
You will perform the jump onto the Klompa's head. He will begin to hurl, but there is only one moment you should be interested in - when the dagger shines at your hands. Squeeze the attack at this moment and end the action with speed kill, plucking up the boss's eye. Remember that if you are late with the attack the giant will dump you to the ground and you will have to clamber up the top of the arena again to jump onto his head.
You got rid of one eye, now it is time for the other. You have to get to the top of the arena with the other way. Run up the stairs onto only reachable platform. Take off to the right, catch hanging bar, climb it and jump again to the platform to the right. Go up with steps, stand under relief. Run vertically over the wall and stick the dagger into the bas-relief. Bounce off to the left getting up the top platform, get onto it and run again to the catwalk. Standing on it press the speed kill mode.
You will jump onto Klompa's head again. Proceed the way similar to previous - push the attack at the moment when the blade of your dagger shines. After successful speed kill you will jump down to the ground. You are passing to the other phase of struggle. The dazzled boss is banging the sword blindfold, but keep away from his weapon and don't let him hit you. Circulate him round and attack his legs from the back. It turns out that he is susceptible to blows from the ground at this stage. A few combinations of blows will be enough to complete the execution of the helpless enemy.
After killing Klompa the massive gate will open and terrified, but grateful to you residents of Babylon will begin to spill out onto the arena. It won't be given to you to hear their thanks however. You will feel that the shady princely nature is beginning to master your body and you will jump into the opening in the middle of the arena not wanting to expose people to the risk of the contact with the Dark Prince. You will change into the Dark Prince after a while.
