How to unlock the The Call of Cthulhu achievement in Call of Cthulhu - Definitive Guide
To get this achievement simply select "I will perform the ritual." as the very last option of the game (end of Chapter 14). Achievement unlocked.
(NOTE: Once you finish the game, you can reload your save to get any other ending available as part of the last option.)
This is the default ending to the game and always available no matter which choices you've made. Select "I will perform the ritual" to unlock it.
Missable.
Depending on your choices through the game, you’ll have different choices of dialogues at the end of the game. To be able to refuse to take part in the ritual you’ll need to:
-Chapter 9 to 14: Always choose the R’leyhian dialogues
-Chapter 10: Submit and Accept the knowledge when talking to Leviathan
-Chapter 10: Save Drake during the Shambler battle
-Chapter 12: Kill Bradley
-Chapter 12: Give the first aid kit to Mitchell
-Chapter 13: Accept the gun during the visions with Fuller
Then in Chapter 14, choose to “Perform the ritual” to unlock this ending.
- First of all, during the initial distribution of points, we throw all the points into the “Search”;
- As the game progresses, we increase the “Search” skill to 100% as quickly as possible;
- Then I brought the “Investigation” skill to 100%;
- After that, I divided the points equally into the remaining three categories.
- I failed the opportunity to get to Warehouse 36 with the help of a distraction with alcoholic sailors and with the help of sewers and got there by agreeing with Kat.
- Not only did I drink every time possible, but I also exhausted the opportunity to drink on every occasion (3 times)
- Found all the occult items
- I told Bradley to stay by the car.
- I accepted Drake's help and saved him in the battle with the Tramp.
- I interacted with all three occult books, but refused to read them.
- I started answering in Rliekh whenever given the opportunity to answer in it.
- I submitted to Leviathan in prison and accepted knowledge.
- I killed Bradley.
- I saved Mitchell and returned to check on Kat (I saw her corpse).
“I gave up the medicine, the flesh, and decided not to kill Fuller.”
- When we tell Irene about her husband: I chose prudence during the conversation in the Mansion, but still drove her to suicide, reproaching her for putting her husband in a hospital.
Tested personally, performing all these actions is guaranteed to give all 4 possible endings and eliminate the need for an additional replay.
