The Talos Principle Developer’s Island
In Area A: Hub Land, go to the Room 7 teleporter. Search the opposite end where another teleporter should be to find Developer’s Island between the boarded up section and the Room 6 port.
Different purple door
Purple doors usually make an error sound when you try to bring an item through them. However, there is one particular door that says something different. Near the end of the game, reach Floor 5 of the Tower. You will encounter a puzzle that requires a mine to destroy a killer turret to progress. After the turret, place the fan parts and use a crate to activate a floor button. Collect the Jammer device, and fly to the area above it. Use the recording device twice to get through both energy fields. Keep the Jammer and continue to a purple door. Have any item, such as the Jammer held as you try to walk through the purple door. This door says “Hello” instead of making the standard rejection sound. Note: You will not be able to take the Jammer through the door.
Nexus puzzle self-reference
Go to the World C Star Room, and solve the Nexuspuzzle by linking the lasers until you reach the end. Then, enable the ” cht_bFly ” code, and move your view above the maze. Look down to see that the lasers you positioned actually spell out the word “Nexus”.
After collecting the Minecraft Diamond Sword, go to the QR code and vines hanging under a huge window in the back of a stone ruin to get a “Slash” option while near the vines. Select the “Slash” option to reveal the QR code. When read with a smart phone, it will display “You Are Not Here” when the Croatian text is translated into English, which is a reference to the game Antichamber .
Fork Parker reference
In Area C: Room 2, go to the ruins of a church with a red door. Walk through that door to enter a black hallway. Go to the window to see Fork Parker’s office. Fork Parker is the fictional Devolver CEO that broadcasts on Twitter.
In Area C: Room 6, enter the first puzzle to the right. Enter the Sigil room that is guarded by a mine. Search the dark left corner covered in brush carefully to find a hole in the wall. Enter it to find the Diamond Sword stuck in a stone.
Papers Please! reference
In Area B: Room 4, enter the Sphinx puzzle room, then turn around. Click the wall of hieroglyphics to find the red Papers, Please logo on the rock door. Go through the first door on the left, and examine the altar. Collect the small green item behind the vases in the left corner. Return to the door to pass through it. Inside is a movie theater where you can watch a short film featuring Serious Sam after you wait a short time.
Pink Floyd reference
In Area B: Room 5, get to the top of the ruin that you arrived in at the start of the room. Note: A box and fan are required to reach the top. Go through one of the teleporters to find a reference to Pink Floyd’s “Dark Side Of The Moon” album cover.
Planet Of The Apes reference
From the entrance of Room B5, travel left to reach the shore, behind an enclosed puzzles. At the waterline is a submerged ruined structure featuring two long tops that are split down the center. Enter the water, and go to the base of the ruins. Examine the underwater sand near the center of the ruined wall that is facing the exterior of the map to find a hidden key. After collecting it, return to the front of the ruins, and use the fallen pillar as a ramp to exit the water and get on top of the ruins. Search near the left corner to find a viewfinder. Look through the viewfinder, and scroll slightly up from its original position to see the partially submerged Statue Of Liberty in the sand.
Portal 2 references
In Area B: Room 2, use the first puzzle on the left to link a red laser with the moon to display the Aperture Science logo. Additionally, in the same area is a hidden key in the nearby puzzle on the right that is used to access a telescope on the high stone beams. Use the viewfinder to get a closer look at the Aperture symbol on the moon to see Wheatley trapped above it.
Serious Sam references
In Area C: Room 1, there are nine statue parts that can be found. When put together, they will create a statue of a Gnaar, a mutant enemy from the Serious Sam series.
Go to the Weathertop puzzle, and make your way around to the back ledge. Look down to where a tree reveals a hidden lower platform. Drop down, and enter a cave that was partially obscured by another tree to discover Serious Sam frozen like Han Solo in carbonite.
You can find the jetpack from Serious Sam by using the following steps. You must first get the star in Area C: Room 3. To do this, start at the “Weathertop” puzzle room, and turn left to find some wooden fences. Notice that one of the fences is slightly lower than the others, allowing you to see the star room. You must collect three Hexahedrons to create stairs in order to get over the fence. Complete the “Weathertop” puzzle to get two Hexahedrons to use, then go to the angled fan launcher that is not blocked by iron fences. Stack both Hexahedrons near the wall, and jump onto the fan, then to the Hexahedrons with a Connector equipped. Set down the Connector, and link a blue laser to lower the force field barrier that was blocking another Hexahedron. Use the three Hexahedrons to form stairs allowing you to advance to the star room. You must then complete four puzzle rooms, and return to the wooden bridge that leads to the castle ruins. Enter the “Big Stairs, Little Stairs” puzzle room. Starting at the entrance, travel to the cliffs along the right edge at the rear. Notice the ledge beneath you that can be reached without deactivating any force fields. Drop down to the first platform carefully, then go to a second platform found to the right. A third platform will be to your left, then a final one along the right edge. Once you drop down you will discover ruins inside a cave. Collect the four sigils in this room in order to bypass the walls. There is a star trap door at the end of the path. Finally, drop down into a water-filled chamber that has the jetpack in the rear corner.
The Lord Of The Rings reference
Just as you enter Weathertop, go to the ledge directly opposite from the entrance. Look down to see a scene from The Lord Of The Rings reenacted by a Gnaar hanging off the edge of the cliff.
The Swapper reference
As you first enter Area B: Messenger, follow the river upstream away from the objective to eventually reach an underwater cave under the outer edge of the map. Pass through it to find a statue head in a cavern after leaving the water. The statue is from the independent game The Swapper .
Easy “Blessed Messenger” achievement
You must work towards the ending that implies you becoming a Blessed Messenger. To do this, collect all 49 red sigils, all 30 stars, and all 9 silver sigils. You must also discover the code to unlock the sixth level of the tower. The three numbers of the code can be found at the start of each Star World. They are written on the board directly in front of the teleporter. A Hub’s Star World’s board gives the first digit, B Hub’s Star World the second, and C Hub’s Star World the third. The code is randomly changed with each playthrough. After getting the complete code, use it to unlock the sixth level of the tower on one of the tower’s terminals. Once there, solve the ultimate tetromino puzzle to become a Blessed Messenger. You will get the “Blessed Messenger” achievement at the end credits.
Easy “Break Down Barriers” achievement
You have to destroy a barricade with an axe. There are two opportunities to get an axe:
In A Hub’s Star World, you can find an axe next to the entrance of the left-most puzzle when entering the zone (“Dumb Dumb Mine”). Use it to break the barricade found in the central ruin of that world.
There is an axe on the wall in C Hub, next to the 7’s world teleporter. Use it to open the barricades found in the A, B and C Hubs (leading to Sacred Grounds), as well as the one located behind the tower that hides a blue source.
Easy “Changed My Mind” and “Eternal Life” achievements
Solve the fifth level puzzle of the tower, then climb the staircase until you reach a kind of platform that runs around the tower and leads to a second staircase. When reaching that platform, do not follow the second staircase or you will not be able to return. Instead, move back all the way down, enter Hub C, pass the luminous gate, then join Elohim and accept eternal life. Note: The point you must turn around is after you walk through the storm clouds, just when he says “I did not warn you out of malice or deceit, I warned you because you are my child!”
Easy “Deal With The Deceiver” and “Take It With You” achievements
There are three possible endings that correspond to possible methods to deal with Milton. You must strike a deal with him, ultimately allowing him to be downloaded with you in the IRL TALOS/SOMA unit. Strike a deal with Milton, then defy Elohim and climb on the top of the tower after finding 49 red sigils. Once at the very top of the tower, choose to internalise Milton, then to transcend. You will get the “Take It With You” achievement at the start of the ending credits. To strike a deal with Milton, use the following steps when he says “Welcome back. There are going to be some changes around here. Do you know what your problem is? It’s that you keep trying to reconstruct fairy tales, but refuse to recognize the holes in your understanding. Thus far you’ve had entirely too much freedom to question my wisdom. From now on I do the talking, you do the agreeing.” You have to agree at least twice with Milton during that conversation in order to trigger an intervention by Elohim and eventually Milton’s proposal to be taken with you when you reach the top of the tower. The correct responses are:
- 1. Any response.
- 2. Any response except “No, I stand by everything I’ve said. These matters are beyond doubt.”
- 3. Any response.
- 4. Any response.
- 5. Any response.
- 6. “You’re right. We’re all just machines with delusions of grandeur.”
- 7. “I refuse to trust anyone, including myself.”
- 8. “We do.”
Easy “Extreme Persistence Detected” achievement
Spend a large amount of time in an unsolved difficult red sigil puzzle without exiting it before eventually solving it. The exact amount of time varies, and depends on the number of interactions and the difficulty of the puzzle. It is always over ten minutes. You must wait for Elohim to tell you that there is no shame in trying again later, then take the sigil to solve the puzzle. You cannot leave the puzzle while waiting for the dialogue to start or the timer will reset. It is acceptable to die, as long as you do not leave the puzzle. Note: Remaining idle in a puzzle will not trigger Elohim’s message. Also, not all red sigil puzzles will qualify; only particularly difficult ones. Consider using Higher Ground, An Escalating Problem, and The Seven Doors Of Recording.
Easy “Free Will” and “On The Edge” achievements
Climb on the top of the tower, which becomes possible after having solving the fifth level puzzle (which in turn requires all 49 red sigils to be found). Note: You do not need to find all the stars to reach the top of the tower.
Easy “Hedging My Bets” achievement
Find all 49 red sigils without spending one in the tower (which is before attempting to unlock any puzzle there).
Easy “Help From Above” achievement
You will have to call one of Elohim’s Messengers for help in any red sigil puzzle. To do this, you first need to wake a Messenger. They are found in the areas located behind the barricades found in each Hub. To break them, use the axe found in Hub C on the wall near 7’s world entrance. Once in the Sacred Ground, solve the various puzzles to open the messenger’s mausoleum and wake him. Afterwards, the messenger can be called for help during any unsolved red sigil puzzle. To do this, interact with the shrine located inside the puzzle and confirm that you require help. Note: Doing this will prevent the “Solipsist” achievement from being earned. Thus, consider waiting until you have found the last red sigil by yourself to attempt to earn the “Help From Above” achievement or use a previously saved game.
Easy “Know Your Limits” achievement
Spend a large amount of time in a puzzle without solving it, then leave. The exact amount of time varies, and depends on the number of interactions and difficulty of the puzzle. It is always over ten minutes. To be safe, wait until Elohim says that there is no shame in leaving the puzzle for another time, then exit. Note: Remaining idle in a puzzle will not trigger Elohim’s message. Also, this cannot be earned in silver sigils’ or tower puzzles.
Easy “Last Stable Version” achievement
As you progress, auto-saves will be created. Load a backup save from the menu to get the “Last Stable Version” achievement.
Easy “Leave Your Mark” and “Split Personality” achievements
You must read a message that was written while you were recording yourself. The first time where this can be done is in World B-4. Collect the can of paint in the corner to your immediate left when entering the large square Sphynx yard. Then, enter a puzzle where there is a recorder unit (paint cans can cross “emancipation grids”). Start the recorder, write something on the wall, stop the recorder, then read the message.
Easy “LOL” achievement
Form the word “LOL” with tetrominos, it must be written out horizontally from left to right and must entirely fit in a puzzle. This requires a puzzle that is at least six squares wide.
Easy “Off The Radar” achievement
Reach the first level of the tower, then return to the ground floor. Note: You do not have to unlock or solve the puzzle located on the first level of the tower.
Easy “Press The Serpent” achievement
There are three possible endings that correspond to possible methods to deal with Milton. This requires reversing the tide with him and pressing him so much that he finally bugs. To do this, use the following steps when he says “Welcome back. There are going to be some changes around here. Do you know what your problem is? It’s that you keep trying to reconstruct fairy tales, but refuse to recognize the holes in your understanding. Thus far you’ve had entirely too much freedom to question my wisdom. From now on I do the talking, you do the agreeing.” You must admit that only one of your beliefs was wrong, and then when you have the opportunity, only answer him with questions to make him rage out and bug beyond repair. The correct responses are:
- 1. “I accept that some of my beliefs face difficult challenges.”
- 2. Any response.
- 3. “There’s nothing else I’m prepared to doubt quite yet.”
- 4. Any response.
- 5. Any response.
- 6. “So that’s it? You’ve given up on everything?”
- 7. “Are you uncomfortable when someone else is asking the questions?”
- 8. “You finished archiving everything. You’ve decided it’s all nonsense. If there’s no more point in anything, shouldn’t you just shut down instead of talking to me?”
- 9. “Are you avoiding the question?”
- 10. “Why does it bother you so?”
Easy “QR Reader” achievement
You do not need to find every QR code. Instead, you have to read at least one QR message from each of the other “main” bots, which are @, Faith, Samsara, Sheep, The Shepherd, D0G, and %Â§&$Â§/$&(#(). With careful exploration and linear game play, you can get the “QR Reader” achievement by World B-7 without having to climb the tower or entering C Hub.
Easy “Sacred Grounds” achievement
You must wake one of Elohim’s Messengers. To do this, get the axe found in the C Hub, then use it to break the barricade found in any Hub. Use the teleporter located behind it to travel to a Sacred Ground. Once there, solve all the tetrominos puzzles to unlock the messenger’s mausoleum. Awaken him to get the “Sacred Grounds” achievement.
Easy “Silence The Serpent” achievement
There are three possible endings that correspond to possible methods to deal with Milton. You must banish (delete) Milton from the system. To do this, use the following steps when he says “Welcome back. There are going to be some changes around here. Do you know what your problem is? It’s that you keep trying to reconstruct fairy tales, but refuse to recognize the holes in your understanding. Thus far you’ve had entirely too much freedom to question my wisdom. From now on I do the talking, you do the agreeing.” Stand your ground and refuse that you might have been wrong in your reasoning. This will trigger an intervention of Elohim that will allow you to delete Milton from the system. The correct responses are:
- 1. “What holes? There are no holes.”
- 2. “No, I stand by everything I’ve said. These matters are beyond doubt.”
- 3. Any response.
- 4. Any response.
- 5. “/banish”
- 6. Any response.
- 7. Any response.
Easy “Solipsist” achievement
Solve all red puzzles without any help from a Messenger. You can free the Messengers, but do not ask them for help at a shrine.
Easy “Transgression” achievement
Reach the second level of the tower. To do this, solve the puzzle found in the first level and interact with the computer that becomes accessible afterwards. Note: To also get the “Hedging My Bets” achievement, do not attempt to unlock the first level’s puzzle before collecting all 49 red sigils, as this will consume some of them.
