How to unlock the Corruption achievement in The Cave - Definitive Guide
In order to get these, you have to play through the game with every character. At the very end you will get the objects you desire (e.g. mini-Sarcophagus for the adventurer, excalibur for the knight, rat poison for the twins.... etc). Simply take them with you. Go on through the door and up the ladder with that object and get the bad ending for this character!
Do this with every character, and you'll unlock this achievement. (Note: For all characters for both good and bad endings you need 6 runs in total)
Plus: You will get two more artworks for that character which are needed for the following achievement:
Technically (if my maths is right) you only need 5 playthroughs to get all achievements.
There are 7 characters, to a total of 14 possible endings (good and bad each). As you can take 3 characters per go this means 5 playthroughs, and one character you take through 3 times (I'd recommend the Hillbilly on that one - to get the fortune teller achievement too).
Plus if you divvy them up correctly - you can get the following two achievements in those 5 playthroughs as well:
For this trophy, you must obtain the “bad” ending for all 7 characters. Follow the same process as in Redemption, except when the clerk gives you your Object of Desire after trading in the trinket, simply walk through the door and up the ladder with the Object in your hand. Do not talk to him again.
Below are the seven Objects of Desire for each of the seven characters. Make sure the specific character is carrying this object with them when you climb up the ladder to ensure they get their respective “bad” endings.
- Adventurer - Treasure idol
- Hillbilly - Pink teddy bear
- Knight - Excalibur
- Monk - Lotus blossom pedestal
- Scientist - Bag of money
- Time-Traveller - Greatest Employee Of All Time trophy
- Twins - Box of rat poison
Required: All seven characters bad endings (at least three playthroughs).
To get the bad ending you need to trade a stolen trinket for your prized possession in the Gift Shop at the end of your visit to the Cave. Then just climb the ladder to leave.
