Jak 3

Story related and cannot be missed.
This will be a boss fight against a giant robot. To defeat him, follow the steps below:
1. Jump to avoid the ripple blasts of energy.
2. Jump to avoid the horizontal beam of energy.
3. Kill the Lurkers he sends.
4. Wait till he creates five beams of energy on the ground. These will rise into pillars. Do not touch them until they have cooled.
5. After they have cooled, jump onto one of the higher pillars and shoot the rail cars that are hovering above him. A couple shots will knock one down onto him.
6. Repeat steps 1-5 three times to defeat him. Be careful, the final time he attacks much faster with the beams of energy.
If your health gets low, use + to regenerate.
