Labyrinthine Chapter 1 Book Locations

[Giovanni Sealy]

Likeits immensely popular predecessor, the indie title takes the form of an elaborate and heavily randomized escape room. In a nutshell, players will have up to six in-game days to break out of a labyrinthine house by solving esoteric puzzles and eluding the titular granny, who is constantly patrolling the hallways.

For the 2019 sequel, the action was relocated to a much larger building and a secondary antagonist was thrown into the mix, known as grandpa. As such, it's considerably harder than the first game, with more convoluted puzzles and an increased chance of being caught by a stalker.

Over time, Granny: Chapter 2 has been updated with extra content, new items and alternative escape methods. Most recently, a helicopter was added to the roof of grandpa's house, meaning that players now have three different ways to beat the game.

If you choose to escape via the helicopter, rather than the boat or the electrified door, then you will need to acquire a minimum of 10 separate objects. The problem with this is that item placement in Granny: Chapter 2 is somewhat randomized, making it relatively difficult to anticipate exactly where you need to go in any given playthrough. That being said, certain items have a habit of spawning in the same locations every time, so you can prepare a little.

To operate the helicopter, you will need to find the helicopter manual, the helicopter key, the security key, a roll of duct tape, a glass fuse, a gasoline canister and a stun gun. In addition to this, you will also need to track down three painting pieces so that you can open the door to the helipad itself.

The first item you are likely to come across is the helicopter manual, which can usually be found in the kitchen right above the starting area. It is often hidden in the cupboard directly in front of the basement stairs.

As its name suggests, the security key is required to get you into the security room. The good news is that this is one of the few items that you can reliably find in the exact same place every time. The bad news is that it is always hung around grandpa's neck.

To relieve him of the key, you can either sneak into his bedroom while he is asleep or momentarily disable him with the stun gun. Depending on your difficulty setting, grandpa will be out of action for anywhere between 15 seconds to 2 minutes.

Speaking of the stun gun, you will need this weapon not only to defend yourself against the grandparents, but also to complete a shooting gallery challenge in the attic. Defeating this minigame, which requires you to hit three moving targets, is a step toward unlocking the balcony door.

To open the door, you will need to track down three picture scarps and assemble them on a nearby display mount. These are probably the hardest things to find if you are planning a helicopter escape, as each piece of the painting can spawn in up to three different locations.

The first can be found on either the dining room floor, in the master bedroom, or in the backyard. The second piece can be found in the master bedroom, on the toilet basin, or the TV room table. Finally, the third piece can be found either in the backyard, on the dining room table, or in the guest bedroom.

Once you have solved the painting puzzle, you will then need to use the glass fuse to deactivate a trapdoor near the balcony entrance. If you do not have this key item, then you will be unable to progress to the helipad and will find yourself dropped right back into the kitchen.

The glass fuse is another object that has a tendency to spawn in multiple locations, although it often appears in the dining room cabinet. If you happen to lose it during your travels, it will eventually re-spawn in the basement.

Meanwhile, the gasoline canister is needed to refuel the chopper. If you are lucky enough, the container might spawn in a locker right next to the helipad itself. Otherwise, it is often found in the ventilation shaft. Once you have it, head over the tail end of the helicopter and pour the gas until the gauge turns green.

It is very important to understand the anatomical landmark of this approach (Fig. 8.1). There are some well-known triangle and skin incisions related to retrolabyrinthine and translabyrinthine approaches (Fig. 8.1a, b).

The retrolabyrinthine approach exposes the posterior fossa dura between sigmoid sinus, posterior semicircular canal, jugular bulb, and superior petrosal sinus. Retrolabyrinthine access to the cerebellopontine angle (CPA) with hearing preservation can be accomplished; however, exposure is generally limited. The most frequent indication for an isolated retrolabyrinthine approach is selective vestibular nerve section. More frequently the retrolabyrinthine approach is combined with cutting temporal bone and splitting tentorium to expose lateral pons and basilar artery from the confluence of the vertebral arteries to the dorsum sellae (the combined petrosal approach).

The head is held with lateral position, facing away from the surgeon. A postauricular incision through the galea is made, one inch behind the postauricular crease. The incision extends from the mastoid tip and curves forward to end just above the pinna (or midpoint of supramastoid crest) (Fig. 8.1d left).

The scalp is elevated by sharply dissecting the subgaleal connective tissue which spans the galea and the underlying pericranium. The pericranium is contiguous with the temporalis fascia above and the fascia overlying the sternocleidomastoid muscle below. A second incision is made in this deep layer composed of temporalis fascia and muscle, periosteum, and sternocleidomastoid fascia to fashion a musculofascial flap that is important in obtaining a water tight, cosmetic closure. The two flaps are elevated anteriorly to reveal posterior edge of external auditory canal, spine of Henle, and root of zygoma posterior point. Large blunt scalp hooks are used to reflect these flaps. The bony landmarks which should be visualized at this point are the root of zygoma posterior point, the spine of Henle, the squamosal suture, the asterion, the supramastoid or temporal crest, the mastoid tip, and the digastric groove (Fig. 8.1c, d right).

The bone cortex is removed within the boundaries of these lines, working anterior to posterior and superior to inferior. After drilling the cortical bone, air cells are encountered. Posteriorly, over sigmoid sinus, the bone will remain compact. In order to provide maximum exposure, wide cortical removal with cauterization should be performed prior to deeper penetration. Gentle, brushlike strokes with the drill will reveal the compact bone of the sigmoid sinus. Bone removal proceeds, 1 cm behind the sigmoid, maintaining a uniform depth as the sigmoid is exposed. When the sigmoid has been skeletonized, the mastoid air cells are drilled away to expose the temporal base dura (temporal tegmen) (Fig. 8.2b).

At this stage certain goals of bone removal should have been achieved, such as exposure of sigmoid sinus and jugular bulb. Exposure of presigmoid dura and middle fossa dura defines the lateral bony labyrinth, clearly visualizing the lateral semicircular canal (LSC) and posterior semicircular canals (PSC) and skeletonizing fallopian canal and exposing the entire facial nerve (Fig. 8.2h).

The lateral and posterior semicircular canals (PSC) are first opened with the drill. The amputated, or anterior, end of LSC is carefully removed, bearing in mind close relationship of tympanic portion of facial nerve. Preservation of anterior wall of LSC will protect tympanic segment of VII nerve. Removal of superior segment of the posterior semicircular canal will expose the common crus which it shares with the SSC. The SSC is also opened by drilling superiorly and anteriorly. The amputated, or inferior, limb of the PSC is followed until the vestibule. Drilling in this area, lateral and inferior to the vestibule, will expose the vestibular aqueduct as it courses laterally toward the endolymphatic sac. The vestibule is now opened by continuing to remove the bone, following the common crus (Fig. 8.3a, b).

The wall of the vestibule which separates it from the internal auditory canal is only one very thin layer of the bone. The compact bone surrounding the internal auditory canal is identified by drilling along the canal at its superior and inferior edge. It is important in terms of maximizing the exposure, to remove the bone around the canal such that greater than one-half of the circumference of the canal is skeletonized. It is important to remove the bone superiorly and inferiorly so that the anterior-most extent of the canal is accessible. Bone removal inferior to the canal will in some cases expose the cochlear canaliculus which communicates with the CSF and perilymphatic spaces.

The wound is closed in the following manner. The incus is removed, and a piece of temporalis muscle is harvested and placed carefully through the epitympanum occluding the origin of the Eustachian tube. The removal of the incus and obliteration of the Eustachian tube entrance by the muscle reduces the possibility of CSF leakage. The dural incision is closed up to the canal, and carpets of autologous (abdominal) fat are positioned in the gaps of the dura so as to seal the CSF space. The previously fashioned musculofascial flap is closed tightly over the adipose graft, and the skin cut is closed in two layers.

The head is positioned (Fig. 8.4a) with the option for skin incision. Using the virtual computer image, it shows the transverse sigmoid junction until jugular vein, in the relationship with the labyrinth and its exposure that can be achieved with this approach (Fig. 8.4b). The next illustration (Fig. 8.4c) shows that dural opening, the neurovascular structure. Be aware that the dural opening is parallel to GSPN at the temporal skull base.
