• The first breach charge is mostly reliable at getting a pistol enemy to walk towards the door to the basement to kill him on my way out.
• Jumping in the water section makes the psycho lose line of sight and stop chasing. The water does the rest.
• There are 3 slow-mo doors in on this mission that are all next to each other even if you can't see them. Sniper support still works, clearing both rooms so they don't have to be entered at the end.
• The second breach charge is pretty reliable at getting the pistol guy
• Waiting a half a second at the final red door ensure the next wave of enemies all walk towards the door. This keeps them on screen for sniper support and triggers the ones that can use the door to chase me sooner.
• Skipping the final two slow-mo rooms and the single enemy between them saves around 13 seconds.
