About

This is a compiled list of all the secrets in signal simulator. Event signals, story signals, and so much more can be found here.
Should any information in this guide be incorrect or outdated, please let me know in the comments!

Having trouble?

Can't detect an event signal? Check the following:

1. Is the time of day correct?
   
2. Is your system time & date configured correctly? Was it reset without your knowledge?
   
3. Have you detected this signal before? Event signals can only be decoded once per save.
   
4. Is your game up to date? Some of the events written here may have just been added in the latest update.

If after checking everything you still can't detect it, try restarting the game. If that doesn't work, let me know in the comments, or tag me on the game's discord server[discord.gg] and I'll help you.

About event signals

Event signals in signal simulator trigger events (duh) to occur in game. These can either be permanent changes to the map, or only temporary changes which disappear after a few minutes.

Don't forget to go outside!

Event signals always come from earth and have the signal type "Radio Signal". Both of these qualities are unique to event signals.

Event signals are hard-coded into the game to only appear at predefined dates and times, and at the same coordinates and frequency every time. To encounter an event signal, change your system time to the date and time listed. The year doesn't matter. You could also just wait, but, who has time for that? Also make sure that the in-game time is correct.

Please note:

1. You may need to restart the game on some occasions if you aren't able to detect the signal.
   
2. If all conditions for an event signal are met, it will be the first signal to appear.
   
3. Once detected & decoded, event signals are not able to be re-detected in your current save.
   
   • Incase you want to create multiple save files, you can find the save file here: C:\Users\<username>\AppData\LocalLow\SOL Games\Signal Simulator. The save file is named save.dat. When moving this file around, you may get a security warning; don't worry, this file is harmless.

Event signals

Rover events

Tips

• Because of how slow the rover is, it is advised to either let the rover execute your commands while you search for signals, or use a program that can speed up the game (like cheat engine's speed hack).
  
  
• If you are able to speed up the game, it is highly recommend you use the golf cart to mark where you think the next pillar will be located, and the run back to the observatory. Do note, however it can be difficult to locate the golf cart through the rover at a (relativity) long distance due to the pixelated, monochromatic camera.

Radiation

There are set distance requirements between the rover and the radiation source. They are detailed below:

Distance	Radiation	Detectable
Above 35 Distance	0.1-0.2	No
Bellow 35 Distance	0.5-1	No
Bellow 15 Distance	1-1.5	Yes
Bellow 12 Distance	1.5-2	Yes
Bellow 11 Distance	2-3	Yes
Bellow 10 Distance	3-4	Yes
Bellow 9 Distance	4-5	Yes
Bellow 7 Distance	5-6	Yes
Bellow 5 Distance	6-8	Yes

Detection

To detect an underground anomaly, preform a science experiment with the rover when you are within range (see table above). To preform a science experiment, use the extend arm command ("AE" in the rover screen).

Beware that if you have scanned the area before, you may not be able to trigger the pillar, despite the high radiation.

Description

Each "pillar" (as they are called in the code) has a devil-horn shape, and has a blue tint to it. They are partially covered in emissive blue lines. They always point towards a central location, which can be used as a reference to help find the other pillars.

Location

The general location of the pillars is right behind the solar panels towards the water tower. The only outlier here is one being along the water tower side of the solar panels. The 8 pillars form quite a large ring. They are ~200-300 distance apart.
I haven't verified this myself, however I was told that the "Pillars" can be found at "bald patches" in the grass. Try looking for these in the area described.
If the above description isn't enough for you, the exact location of the "pillars" can be found below:

Big thanks to sherlock111 for this image.
(Original can be found here.)

Event

Once all 8 pillars have been located, a huge spaceship will rise out of the ground at the center of where the pillars "point" to. The space ship has it's own colour pallet, separate from the pillars that trigger it.

Pillar Event

Each pillar has a button attached to it. The button has a green glow to it. Pressing this button causes the pillar to glow blue-purple. This colour change is paired with a drone noise that sounds like the pillar is charging. Upon activating all 8 pillars, the mothership will charge a blue laser, and will proceed to fire it to the ground. After several seconds, the ship will disappear. If you go to where the beam was fired to, you will find a plate with a transparent orb around it. Standing on this plate will teleport you onto the mothership that just departed. You can return to the observatory using a similar looking orb on-board the ship. Don't worry, you can return to the ship as many times as you like.

Other Radiation sources

• There is radiation around where the shoe is found. Scanning this area seems to have no effect. This radiation source is only present if the shoe has not yet been picked up.
  
• Similar to the shoe, radiation can be found where the recorder are located.
  
• Meteors can be found around the map. These are randomly generated. There is a limit of one at a time. A new one spawns when the existing one is scanned. Meteors can be identified by green gas coming from the ground.

Story signals

Story signals have a 10% chance to appear when scanning a signal, and will do so in a random order. Duplicate story signals are possible.

These are in the order as they appear in the code, which appears to be the chronological order.

Miscellaneous secrets

These secrets you can find around the world. These can be found right when you create a new save.

Shoe

There is a rock near the observatory. On the other side of this rock you can find a shoe. This is a collectable item.

Recorder

There is a recorder by the water tower. This is a collectable item.

"Dead" Alien

There is a "dead" alien between antennas 11 and 12 between the tracks. This is a collectable item.

Alien Pods

A room full of alien pods can be found in the warehouse building by the antenna in the maintenance building. You can easily identify the location by a hole in a wall with blue mist on the other side.

Random alien encounters

VHS Player

While sitting at your desk, there's a chance for your VHS screen to briefly display an alien standing behind you.

Bathroom Window

At night, when opening the bathroom door from the bedroom side, there is a small chance that a alien will be standing there looking at you - but will slowly move down, out of view.

Garage

At night, there is a small chance for an alien to... we don't know what it does. Party? Experiments?

Maintenance Antenna

At night, there is a very small chance for an alien to tamper with the antenna in the maintenance shed. While you can't see this one, you can hear it. It will sound like banging and scraping.

[(SEX)]

"Check the bathroom" will always be ingrained in my memory

[heronbrai007]

For the rover events i have a very good tip: While the rover is moving you can push it backwards and fairly quickly but not that easy to control

[artmaster82]

I never actually noticed that. Thanks.

[star_krafter]

btw a thing to add to the "rover events" is "An easy indicator to determine where the location of the spikes are is to look at the grass. If there is a circular patch where there is no grass, then that is probably where the spike is."

[LocustTheLorde]

H3lL0? iS Any0n3 Th3Re?

[LocustTheLorde]

I appear to have lost your signal, dang... Seems like either the government or the greys got you, that's not good... Welp, time to be alone for who knows how long again..

[LocustTheLorde]

Cool, At least that giant spaceship that came out of the ground and shot a teleporter in to the ground disappeared along with its pillar friends. I thought the helicopter was gonna report it to the government, and they were gonna do something to me. Thank god it disappeared.

[artmaster82]

I think only we know about it. Doesn't seem like we're being monitored besides our grey friends.

[LocustTheLorde]

Thanks, Elon's booster had arrived in my site and I have no idea what to do with it. No one has come looking for and I don't know if the government is aware of the booster here, any ideas my friend?(and yes this is a joke

[artmaster82]

Your welcome. For spoiler tags, you can find out how to use them (and more) under "Formatting help".
