Jak II

This trophy is story-related and cannot be missed. This mission is obtained from Krew.

After being introduced to Sig, an experienced soldier, you will head to the pumping station back in the slums to take out a few rowdy Metal Heads (this is the first mission whereby you can begin collecting Metal Head Gems, check Head Master for details). This mission has quite a difficulty spike from the previous ones so make sure you use your newfound weapon wisely so that you don't die. Sig shall lead the way and numerous times will have to charge his Peace Maker to zap a Metal Head, when he's doing this make sure to protect him from other enemies as he has a health bar too. When he shoots the last Metal Head (and you suffer through a mini-ambush), you'll earn this trophy.
