Chapter 5: Checkpoint 6. Aim assist set as [FREE AIM]. Right when you gain control, run up the steps to the left and skip the cutscene. After the cutscene, shoot the barrel near the steps to trigger the cutscene then quickly kill the remaining enemies.
* It seems this exploit has been patched and you can't shoot the barrel anymore, you will have to kill all with just your bullets. Best done on Easy setting.
