Jak II

This trophy is story-related and cannot be missed. This mission is a continuation of the previous one.

The best weapon to use for the duration of the final battle is the Blaster gun. For the majority of the first phase of the fight, Kor will implant eggs which will hatch the scorpion Metal Heads. Dispose of these as they're impossible to ignore. Whenever you get the chance, shoot at Kor to slowly chip off his health. Kor will shoot a laser at you periodically but a mixture of rolling and running easily evades this.

When the second phase begins (when one-third of his health is gone), all that will change is Kor will do a double laser attack now, and flying Metal Heads will attack as well as scorpion ones. Make sure to deal with the flying ones first as they're harder to evade.

The final phase switches things up a bit. Kor will crawl after you now on the ground and you'll no longer have to deal with other Metal Heads. He now has a triple laser attack and one other new move, where he'll send ripples of energy out towards you. Hopping over them easily evades this. He moves pretty quickly so look back every so often to shoot two or three bullets, and don't let him catch up or things can get nasty.

When you finish him off, after the final cutscene, you'll unlock the trophy. Congratulations for finishing the game!
