Eldritch is a randomly generated first person action adventure game and contains a number of places to explore.
The LibraryEditThis is the hub of Eldritch. It is filled with books that offer clues as to the nature of the game world.
There are three glowing books which allow you to access the three main worlds of the game and a chest in which you can store and access "artifacts" which act as the game's form of currency. The "Mountains of Madness" expansion adds a fourth book leading to the eponymous Antarctic mountains.
At this time it appears that the Library is randomly generated, or at least was randomly generated once and now is locked to that layout once you start the game. There are no monsters in the Library and it's 3 stories tall.
DagonEditThis is the first world that the explorer can access. A book (with accompanying Compass) can be found in the beginning area, which tells about this world, a temple to the water god Dagon.
Enemies that may be encountered in Dagon include Deep Ones, Bugs, Snakes, Dagon Cultists, and in later levels, Flying Eyeballs and Shoggoths.
Hazards that may be encountered are spikes, harmless when walking through them, but deal 2 points of damage if running through or jumping into them.
This world contains a lot of loot, which will be useful when exploring later worlds. Fountains also seem slightly more frequent than in other worlds. It is best to start out in Dagon even after all the books are unlocked because the player can easily stock up on bullets, which will be very much needed in the two other worlds.
This is the second world of Eldritch, and considered to be the most difficult of all the three worlds due to how dangerous the Denizens are: Mummies that rise again when killed, Lizardmen that jump, dodge and spit, Fire Bugs that shoot fireballs, and Lizardmen Statues that attack when not observed, and are invulnerable to conventional damage (except for explosives).
Enemies that may be encountered in Nyarlathotep include Lizardmen, Lizardmen Statues, Fire Bugs, Mummies and Nyarlathotep Cultists.
Hazards that may be encountered are trip-wire traps that deal 1 point of damage, unstable floors that collapse when stepped on, and spikes.
The Tripwire Gun can be found in Nyarlathotep, as loot or in stores.
The third area of the game, R'lyeh, is an sunken ruin flush with plant life.
Enemies that may be encountered in R'lyeh include the Star Spawn, Flying Polyps, R'lyeh Cultists and Deep Ones (harmless).
Hazards are plenty in R'lyeh. Notable hazards include eyes on floors and walls that explode in poisonous gas when the explorer is near, spike walls, floor spikes and tripwires.
The creatures here are resilient with many hit points, though they lack the "tricks" of Nyarlothotep's enemies, making them easy to kill.
The Endless LibraryEdit
The final portion of the game takes place in the same library you start out in. To reach the Library stage, one must collect all three souls from each of the three worlds, and place each soul on the three pedestals opposite the books. The door will open and the explorer can enter the second part of the Library.
Enemies that may be encountered in the Library include all Denizens from Dagon, Nyarlathotep and R'lyeh.
Located in each of the three levels of the Library are candles. Lighting all three candles before reading the book in the final level gives the explorer the Good Ending. Failing to light all the candles leads to the Bad Ending.
There are no hazards in the Library other than menacing heights.
This world can be found in Dagon, Nyarlathotep, and R'lyeh by discovering a secret room containing a Dusty Book. This room is only found on one floor in each world (commonly on floor 2), and can be difficult to reach without mining its walls.
Each Shadow World contains a number of Artifacts and a unique piece of gear, none of which grant the player any special power. However these items are needed in order to achieve the Great Ending.
- Holy Symbol
- Consecration Kit
The order in which they are found appears to be randomized. These items are referred to in the Librarian's journal entries, which may be found in the Library.
Mountains of MadnessEdit
The expansion adds a new level in the Antarctic mountains based on Lovecraft's novel At the Mountains of Madness. The level is predominated by ice and snow and contains several new items, enemies and traps.
Penguins, Elder Things, and Mi-gos are some of the Denizens that may be encountered in this world.
The new items include a pickaxe that digs through blocks, a hatchet that chops down wooden doors, and a Grappling Hook that shoots a climb-able rope anywhere.
There are also many icicles scattered all over the ceiling that will fall down upon the player as soon as they walk underneath them.
Health is also extremely rare; getting progressively rarer the farther one descends. There is no fresh fruit or baked meat (only in occasional shops,). Instead, there are camping fire pits that restore 1 hit point when activated, and can be rekindled with a Fire just scarce camping fire pits the player occasionally stumbles across.
This world takes on multiple drastic appearances depending on the tier; the icy mountains only in the first few levels until the appearance takes on other forms, including what resembles an underground mushroom forest.
The Mountains are more challenging than the other original three worlds due to the scarcity of resources, abundance of enemies, and the length of the world itself. If you are collecting all three soul orbs, this world can be passed over and is not mandatory.
To leave this world, the explorer must descend all 10 levels to retrieve a pair of plane keys, located on an altar surrounded by Cultists, then ascend all the way back to the surface level, granting the What Final Horror achievement.
Note that when the keys are taken, a black cloud (the soul of the airplane's original owner) will follow you, making noises. The cloud is harmless, but it may "cloud" your vision.
Completing the Mountains of Madness (returning to the plane with the keys), will end the game, restart the player with default spawning statistics (i.e. 3 hp, 0 artifacts, 0 items, etc.), and will wipe the player's progress in other worlds. In other words, completely restarting the game. If the player wants to experience the Mountains of Madness and return without wiping their game, the player can search for the hidden book portal, found somewhere near the bottom level, where the cultists are guarding the plane keys. The player may have to use dynamite or a pickax to find the hidden room where the book portal is. The book should show up on the mini-map if the player has the Compass equipped. Regardless of whether you pick up the keys, the black cloud will not follow you back to the library or any other world. If you pick up the keys before leaving, you may return to the bottom floor of the Mountains of Madness from the library at a later time. This is useful if you wish to get the R'lyeh Nice to Meet You and What Final Horror achievements during the same life. If you do not intend to return to the Mountains, you still retain all of the items and upgrades (fountain boosts/spells) you acquired there.
Trick or TreatEdit
A Jack-o-Lantern can be found in the library canteen. Activating the jack-o-lantern will send the explorer a strange, black world.
There are only two Denizens that may be encountered in this world, Jack-o-Lantern Cultists and Shoggoths (lots of Shoggoths).
This world is full and plenty of artifacts, keys, food and ammo. There are small Jack-o-Lanterns that can be destroyed to yield a pile of artifacts. There are piles of weapons and tools like Tripwire Guns, Grappling Hooks, Pickaxes, Dynamite and Hatchets. The Oily Statue is also present, granting the "Summon" spell if prayed to.
Unfortunately, guarding all this bountiful loot is a large number of Shoggoths. These ones are fast, requiring the explorer to grab whatever loot is found and run for it, and like other Shoggoths are invincible, making them more of a hazard than an enemy.
Escaping this world is done by activating a giant Jack-o-Lantern located on the bottom floor, which will take the explorer back to the Library, along with any loot she is carrying.
Like the Mountains of Madness levels and the Asylum, the Trick or Treat world is completely optional if the explorer intends to collect all three souls.
When relapsed the developer Dphrygian described it as "This spooky level is absolutely packed with loot. Use it to gear up for adventure! Or work on that 9,999 artifacts achievement".
