Chapter 7: Checkpoint 9. Load the game with your aim assist set as "Free Aim". There will be four enemies on the ground, two on the second level followed by three on the third level. Take out the four enemies on the ground first, then turn to your right and kill those two dudes. Then turn to your left and kill the guy running up the stairs followed by the two guys on top.
If you want to make it a little easier, try shooting the guy in the middle on the third level then the guy coming up on the steps.
Here's a video guide for you guys to follow.
