Equip Crowbar, Brawler, Both Time Bonus Bs and both Speed Ups
Run upstairs (crowbarring anything in your way), gank the Yellow Key moldie in the TV Room, run back,
Don't go back in the keypad room, instead take the collapsible stairs up, through the Clancy Room (killing as you go) and sprint for the Blue Blaster. You should have just enough to time to grab it and take out the arachnid that will be leaping from your left.
Using the Blaster, execute the Red Key Scyther, drop down into the elevator area to take out the two molded there. Snag the Dulvery Cru (middle bottle) and run up the stairs to take out the two new spawning molded. The moment they're down, look up and shoot the bobblehead circling the central junction.
You should now have at least 3 minutes on your bonus clock. Starting with the Safe Room, gather up food and make recipies+feed Jack as normal. Avoid coming back to the Catwalks and be careful in the hallway by the corner room - these are the places arachnids spawn, and they can be tricky to take out with the crowbar.
