Jak 3

Story related and cannot be missed.
You will be using the turret in Spargus for this mission. Your goal will be to defeat all the invaders without being destroyed by their bombs. This will be tricky; you will have to tank some shots so that you are able to destroy the robots. Each robot will have 5 areas that need to be shot several times before the robot is destroyed. These areas will be marked by faint red targets, and will disappear after you have done enough damage. Make sure you don’t get hit by too many of the bombs they shoot at you, or you will be destroyed. After you have defeated all the robots in the ocean, you will have to defeat 3 inside the city. Once that is complete, you will receive this trophy.
