Destroy Dark Ship Shield
Shields are Down
It is also related to a trophy titled Shields are Down, completing this mission will reward you with a bronze trophy.
During Act III, Jak adds the Time Map to the Astro-Viewer and mentally links into the Dark Maker Ship, using the Dark Maker Bot to disable the ship's shields. This is the only time Jak uses this bot to perform various actions, such as killing Dark Makers, bashing walls, and handling heavy objects.
The shield system takes the form of a greenish-gray, electrified, gooey, cocoon shape. There are masses like this through out this section of the ship and Jak must throw Dark Mines at them to activate the machinery. The shield cocoon is about three times the size of a regular one and it has about 3 hovering orbs that seem to be pieces of the main part that when hit with the mines move around faster and after being hit a second time are destroyed. After all of them are destroyed the larger center one explodes causing the shields to drop.
