Jak 3: Part 34: More Metal Head Hunting with Sig
After you're done getting more Precursor artifacts for Sig, you get to do some more missions with him, using the Gila Stomper once more, of course.
Go back to the Meta-Pede nest entrance to meet up with Sig. Those Meta-Pedes have fully grown-up and have a Light Eco Crystal, so now it's time to hunt them down!
There are 5 of these Meta-Pedes. You can only damage them by shooting their undersides when they rise up. The annoying thing is that they'll constantly dig themselves underground, and they will sometimes stop in place to shoot at you.
Shoot them all down, and the Light Eco Crystal is yours!
----------
On the way out the next, Jak finally confronts Sig about him being Damas' spy in Haven City. Damas sent Sig into Haven City to look for something he lost years ago. So far, it hasn't come upm yet.
Something horrible is going to happen to the entire world soon, and Sig believes in Damas' plan to protect all of Spargus City from it, even if it means Haven City falls, especially with that city's ongoing war with the Metal Heads and KG Bots. To Sig, it's all about "Survival of the Fittest", and he only wants to follow the strongest side.
Now what this horrible thing is? We'll have to find out later...
----------
Go back to the vehicle garage, and Kleiver will be waiting there. There are more artifacts to finds, but Kleiver gave them away to some Metal Heads. If Jak wants them back, he'll have to go back out to the Wastelands with Daxter and Sig to find and hunt down those monsters.
This mission will be an automated FPS sequence where you use the Gila Stomper's turret directly to shoot at Metal Heads while Sig is driving the car. Shoot any and all Metal Heads that you come across, but also shoot down any projectiles they launch at you.
The last running Metal Head you kill should have another rare artifact: The Quantum Reflector. You'll need that for the pillar in South Haven Forest, too.

There's a special Kleiver challenge where you have to kill as many Marauder cars as you can within the time limit. The higher your kills, the more Precursor Orbs you get.
