Jak 3

Story related and cannot be missed.
Once back in the Forest, you will be tasked with destroying 9 Dark Eco Plants. Simply jump in the closest turret, after shooting its previous owner off, and destroy the plants by shooting at them. Careful not to die from attacks by the enemies the plants spawn. Each turret can see, and destroy, 3 plants. Don’t worry too much, if you fail at any point, you will only have to repeat the last turret that you are on, the previous ones save. After you have defeated all 9, head up to the top of the Precursor platform and watch the cutscene for this trophy.
