Dok-Ock Boss: Two generators are at both sides of the screen.

The tridium powered sun will pull boxes with its gravitational force. Grab the boxes and throw the at either generator.

When one is destroyed Dok-Ock will leap down and try to fix it.

He will send out a shockwave as he lands that only stuns you.

Then you run and start attacking him.

CAUTION: Generators fire ranges of bullets at you and if you are hit the box in your hands will be destroyed.

Repeat this process until he is fully defeated. Congratulations now you can fight with Dok-Ock.
