Credit for this entire strategy goes to Baefu and his friends. Detailed Plan Below:
Team Comp: Leatherface, Cook, Hitchhiker
LEATHERFACE
Start: Go left to West Tunnel, then left and around to the right through the Northwest Tunnel (break barricade if it's there), and go past South Storage Room (Lean-to Basement Door)Follow the path straight through Pump Storage and open/break the door to be in front of Tool Storage (Grandpa Shack) Basement Door.
If Grandpa isn't awake yet you can break the Door near Furnace (or the barricade that might've spawned in pump storage), but otherwise be ready to immediately go upstairs from there.
**Alternatively you can just go straight from your spawn through the Central Tunnel and make a left to get to Tool Storage Basement Door faster. Adapt based on how fast they gain 250 points (like if Connie used her ability right away).
Once you are upstairs make a left out of the opening in the shack and break the crawl space near the Gate that's outside the right Facility Door. Also break the crawl space in the Grandpa Shack (Tool Storage Shed) if you can, then break any high-priority barricades nearby.
COOK
Start: Ignore blood. Leave from the Facility Door that's further from the Garage and Padlock it behind you. Padlock the GATE in front of the Garage. Immediately run to the Ramp in front of the Slaughterhouse Sliding Door and begin to listen and call out Victims to teammates.
*Our cook uses the "Faster Listening" Level 3 perk instead of the one that marks Victims for teammates. This way you can track them in 2 seconds instead of 4, but it requires more communication.
*Don't worry about the 3rd padlock, you can hold it. Victims can rush so fast you actually don't have time to use it early on against a good team.
HITCHHIKER
Start: Leave through the Garage-Side Facility Door. Trap the grass side of the Gap that leads into the Garage (so they will be trapped if they try to Gap to the Right Facility Door from Garage). Go through the Grandpa Shack (Tool Storage Shed) and place a trap in between the Red Gate that leads to the Blue Container (this is on the way to Cattle Chute). Place your last Trap in the Right Opening of the Grandpa Shack next to the stairs that lead to the Basement.
When not reacting to Victim callouts you want to always patrol near the Grandpa Shack so you can be near your traps.
HOW THIS WORKS
Victims will have no way to get to the Fusebox without either lockpicking the Gate or going past a trap. They also can't get to the Right Side Slaughterhouse Door so you won't have to check it until they breach your traps. This is because the crawlspaces that go around will also be destroyed by Leatherface. The only chance for them to sneak around this is to use the Roof of the Grandpa Shack (from going up the ladder).
You still need to keep track of Valves and Fuses when possible but this is probably the best way (currently) to slow Victim progress on the map.
