--INFO--

This is divided into section 1 and section 2, separated by the wooden passageway's portal in the center of the last platform. Skulls require 50(?) kills nearby.

--Section 1--

[S] Starting Room (table)
This starting room has a bowie knife, which you can do the round 9 point save strat with. Not really needed since you have plenty of points by the minimum round you finish the skulls, but is worth thinking about. You can jump over the table and through the window, which can save you sometimes. Unlock the door.
[S] Below Deck of Starting Room (near lamp)
You will need to unlock the log door to the left of the starting room to continue your progress on the skulls. Note the last two skulls in the list are in a tougher position to hold, so you may want to go to those two before doing these four. Also, you'll get the mystery box earlier, and the wall weapons are not too good in this map. The skull to the left of the house and the first skull in section 2 are also in a tough position, so if you wish you can do those two too.
[S] Left of Log Field (on campfire)
[S] Right of Log Field (underneath tree, besides roots, can be seen from the far room's direction)
Open the far room (bar).
[S] Middle Bar (left side of room, entrance's angle; not on wall)
[S] Stripper Pole Stage (exact middle)
Now, the last two are through a buyable door (wall) back to the right side of the log field, on a wall close to the entrance door you bought (and a second buyable door).
[S] Middle of hill (upper section of the previous outside of starting room, the door between should be automatically opened when you bought the previous door. Near the middle).
Unlock the second buyable door at the far left part of the new area, facing the entrance. This long pathway has a spawn behind you, so be careful.
[S] Passageway between Circular Wooden Platforms (near the center)
After all skulls are done, you are free to continue to section 2's portal. You can return at any time with the portal in section 2.

--Section 2--

This area is more lit, making training a bit easier. There's no really good camping spots until you unlock the mystery box area. I recommend rushing to the mystery box and rolling until you get the ray gun mark 3 (the two gun one), because the ray gun ray kills until very high in rounds and the slow down orb helps prevent any sudden no escape moments when you are focused on what's in front of you, which makes skulls much easier. You can wait at the dropdown near mystery box at the start of rounds to let the zombies spawn and prevent getting trapped. No stamin-up until later and random zombies inside the corn make this extremely helpful to prevent dying. Drop down when you need to, be careful of the right side's zombies.
[S] Just Behind You (near the center of the barn you start this area in, besides some barrels).
[S] Second Floor of the Barn (up the stairs in the barn, facing the house, in the center).
[S] Besides the Truck (in front of the barn, other side from the exit).
[S] Behind the Shed (left of the truck, right of the double door).
Open the door at the far end, to the left of the house. It's 10 points.
[S] Left of the House (the open field to the left of the house, just past the red rock).
[S] Middle of Living Room (First room when entering through the double doors, other side's couch).
[S] Upstairs Below the LMG Wallbuy (also right of jug, and right of the entrance of the room).
Open the door to the shed.
[S] Left of the Double Doors (near a tire).
