Star Wars: The Force Unleashed II

Gorog is the boss in the fourth level. In the last stages of the fight, you will chase him falling down to the ground. As you fall, you’ll run into debris AND flying Stormtroopers. Avoid them by Force Push and dodging, stay in constant motion. There is a wall as well, use Force Push to open up the hole in it. This is actually a very short segment, which will end with the camera zooming in on you (and when the Gorog's health reappears again - thanks Duality26 for this tip!). If that happens, and the trophy doesn’t unlock, simply exit the game to the main menu, then choose “Continue,” you will start from the beginning of the fall.
