This page contains all of the parts you will see and manipulate in The Talos Principle. Although there aren't many, you'll find that each time they're used it's to serve a different purpose, to combine the elements in a different way.
Jammers EditJammers can be used to prevent the operation of one energy wall, turret, fan base, bomb, or buzzer. They can operate from any distance and can track a moving object, but they need line of sight, or they'll stop operating. However, if they regain line of sight, they will operate again.
- [Spoiler] Getting jammers through gates:
- [Spoiler] Jamming what should not be jammed:
Reflectors EditReflectors can be attached to any number of other reflectors, coloured light generators, and coloured light receivers. When you then place them on the ground or on a hexahedron, the reflector will send beams towards all of these objects (and generators send beams of light towards the reflector) until it's picked up again. If the beam of a reflector strikes another reflector's beam, the two will cancel out. In some cases, this can be used to create a cycle of reflectors causing walls to open and close in sequence.
- [Spoiler] Not all walls are impenetrable to beams:
Hexahedrons EditThe hexahedron is a strange shape that may appear to be a cube, if you don't look too closely at it. If you do, you will realise that it is actually a hexahedron, which is a polyhedron with six faces. Totally different.
Hexahedrons may be jumped upon and stacked. You can jump onto one hexahedron, but jumping onto a stack of two requires more elevation, such as a third hexahedron to get a step up.
Fans EditFans are not operable without their bases, which is on the right, and their bases must be powered, such as by a receiver or a wall switch, or sometimes automatically. Some fans cannot be removed from their bases. However, fans themselves are weighty enough to push down a pressure plate.
The amount that fans push depends upon their base; some will push just a bit, some will push far. If a fan pushes upwards, you can ride on top of it. Hexahedrons may also ride a fan, and multiple hexahedrons may be stacked. However, other tools will fall off the air stream. To ride a reflector or jammer on a fan, you need to put them on a hexahedron first.
Playback EditThe playback tool allows you to record up to five minutes of movement (but not through an exclusion field) when you use the tool. When you use it again, a simulation of you will do whatever you did while recording, until the recording ends, until you die, until the recording dies, or until you walk through an exclusion field. During playback, all tools have doubles, that you can't initially see until you move your copy of the tool. This allows you to double the number of tools you have available, with one major limitation - you cannot ride a playback hexahedron.
Platforms EditPlatforms are used with the playback tool during recording to provide for your future self a place to stand on. During playback you'll need to be high enough to be able to jump on the platform, or put tools on top of it.
Environmental tools Edit
There are some things in the environment you will need to manipulate with your tools.
Pressure plates EditPressure plates can be stood upon to cause them to activate something, such as to turn off an energy wall. You can also weigh them down with reflectors, hexahedrons, jammers, or fans. Platforms and anything else you can carry are not heavy enough, and bombs and buzzers float, so they don't activate pressure plates.
Wall switches EditWall switches are used to disable energy walls, disable turrets, and perform other actions.
Generators EditGenerators are sources of red or blue light that you can connect to a reflector, and connect that to a receiver to manipulate the puzzle.
Receivers EditReceivers take light from a generator that has been bounced off a reflector. When they have power, they perform different actions - primarily, they turn off energy walls and activate fan bases. They need to be matched to the correct colour to operate.
Tools of Opportunity Edit
You may find some other objects of use in your environment.
Keys EditKeys can be found in some tests. They may be able to open one or more than one locked gates. They will be dropped if you pass through an exclusion field and returned to where you picked them up.
Paint EditYou can often find buckets of paint in your environment. If you bring it to a wall, you can use the paint to write a message on it.
Axe EditYou can sometimes find this rad axe laying around. If you pick it up, you will look really cool. And if you can get to a playback tool with it, you can pretend to have an axe fight with your former self! Or you can drop it, too. [Spoiler] Or if you want to use it for something...: [Spoiler] And if you can't go around it...:
There are a certain number of enemies you will need to use your tools to circumvent or deal with, or parts in your environment that can be used to accomplish your goals. While they can kill you, understand that that is only their programming, and they do not bear you any ill will.
Bombs EditBombs are floating black spheres that generally move around in a set pattern, although some are still. If they get close enough to you, they will suddenly fly towards you and explode, killing you. You will be killed regardless of your radius, so if you were to drop down a hole right before the explosion, you'll still die.
Bombs can be temporarily disabled with a jammer. There are some more tricks you'll learn as you play the game:
- [Spoiler] Misfire:
- [Spoiler] Stacking:
- [Spoiler] Blocking their movement:
- [Spoiler] In range and out of danger:
Buzzers EditBuzzers, like bombs, are floating spheres that generally move around in a set pattern. However, they will not attack you, although you can die if you run into them often enough. Most of the time, they are there to interrupt reflector beams.
- [Spoiler] Stacking:
- [Spoiler] Blocking their movement:
Turrets EditTurrets are weapons that, if active, will scan a conic region in front of them. If they spot you, they will start beeping, and if you are close enough they will fire and kill you unless you manage to get out of their sight. There is a blind area beneath them, and the angle for the cone of their view is not very wide, meaning they can only see mostly what's in front of them.
Energy walls EditEnergy walls are blue barriers that block all movement and reflector beams. They may be disabled with a jammer, or there may be one or two receivers that can disable them.
Exclusion fields EditExclusion fields are purple regions that you can pass, but if you have a tool in hand, it will be dropped. They are the boundary into all tests, and are sometimes used within tests as well. The field also stops recording or playback. You will not only drop keys, but they will be returned to where you got them if you try to carry them through an exclusion field. Only paint may be carried through the walls.
Locked gates EditLocked gates may be opened with keys.
Wooden barriers EditWooden barriers sometimes block your way. If only there were some way to remove them, such as with a flamethrower! [Spoiler] An axe can make short work of a wooden barrier. Most will stay dead, some will come back.:
Sigil locks EditSigil locks are puzzles that require the correct number of sigils of the correct colour. They must be organised on the grid so that none overlap and all spaces are filled. Most of the puzzles have multiple solutions beyond simple symmetry and rotation.
Trees EditWhy would a tree be an obstruction? Just go around it, you doofus! [Spoiler] Or if you can't go around it...:
If you manage to complete a test or puzzle, you may be rewarded.
Sigils EditSigils are rewards for completing a test. Elohim will tell you sigils are the letters of his name. Perhaps that is true. They are also, completely coincidentally, tetrominoes. Sigils can be green, yellow, red, or gray. Green sigils allow you to progress to new lands and areas. Yellow sigils unlock tools. Red sigils are used in the Tower in defiance of Elohim. Gray sigils are a mystery to be solved. [Spoiler] The use of a gray sigil:
Stars EditStars are an additional reward that you can find in some areas, or perhaps in the Nexus or the Tower itself. When they are within an area, you may know how many stars are present by the sign at the start of the area or before its teleporter. Stars may be found in a test or outside of them. They always require imaginative use of the tools you have available to you.
Some objects in your environment are there for you to learn more about other characters in the story, or to interact with some of them.
