There are three achievements for collecting data snoopers in The Signal from Tölva:





This guide lists all snoopers, the regions in which they can be found, plus specific descriptions of their locations. If you have any problems finding any of them or if you notice a mistake, please let me know in the comments and I will try to help.

This is my first guide, so please be gentle with your feedback! If this guide helps you, please rate and / or favourite it.

Data snoopers aren't particularly hard to spot as you roam the wastes of Tölva (until you realise you're missing your last one). These tips should help you spot them naturally as you play.

The three proximity sensors on your HUD from left-to-right show signals (blue), resources (yellow) and snoopers (red). The red sensor is the one we're interested in.



As you explore, keep an eye on the sensor. If you see a sliver of red, you are approaching a snooper; explore the area until the bar thickens. When it has reached a full square, you are very close.

Your proximity sensor has a range of 175m so you should be able to pick up most snoopers naturally as your explore Tölva. However, if you are having difficulty, remember that snoopers tend to be hidden close to cliffs, so try not to stray too far from the outer walls of each region.

Activating your scanner will also help find snoopers, as they emit a signal field which can be seen from afar.

Snooper locations are listed by region. The descriptions should give enough of a hint without spoiling the experience of searching for them.

Collecting all 37 of these will make you a Master Surveyor.

If you'd prefer to see the exact locations without exploring, AEon has a nice World Map guide which shows various items, including all Snoopers: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1317692766
