There are many guides on the internet for their location.

Searcher

Runs the same way as Observant and Treasure Hunter.


Treasure Hunter
Find all the caches in the game.
It is performed in the same way as "Observant" and "Researcher". But for some reason, it was fulfilled for me when I was collecting even those secrets that were already there, in other words, this is a collective achievement, it doesn't matter if you find all the secrets, or if you pick up old ones, it will still count them.

Engineer
Purchase all CLN weapon upgrades.
With an increase in the level, you will be given improvement points, invest everything in the branch of conventional weapons and your achievement.

Electrician
Purchase all N.R.G. weapon upgrades.
It works on the same principle as the "Engineer", you invest everything in the branch of energy weapons and your achievement.

Armoured
Purchase all equipment upgrades.
It works on the same principle as the 2 top achievements, you invest everything in the branch of improving your body and your achievement. (I advise you first of all to pump the radar for nanites and enemies, it will become much easier to play and pump).

These 4 achievements are exactly the same. You need to destroy the Atlanta, simultaneously shooting back from the mini-bots that he emits, at this time, by the way, he is invulnerable, so first destroy the small ones before shooting at Atlanta.

The next 5 achievements are obtained in the 7th mission in the Hospital. "Eagle Eye" can be obtained at the very beginning of the mission, you can see the achievement for this video:










The other 4 are the same. In them you need to destroy the main boss on the roof of the hospital.

Exile: Shock'em!
Detonate 30 nuclear elements.
All you need to do is destroy 30 barrels with nuclear elements, but in the company of these barrels there are few, and in the Arena (the last mission of the add-on) they are not counted, as are nanites for opponents (that's right - you will not be pumped by killing opponents in the Arena, even they won't give you anything for the Overseer). Therefore, somewhere you have to go through again.

Exile: Wanderer
Complete all episodes of Wasteland on Medium difficulty or higher.
You just need to go through additional missions, at the end of which the final boss "Watcher" and the final cutscene are waiting for you. The Hermit: The Discoverer Complete all episodes of Wasteland on Hard or Hard.

Exile: Discoverer
Complete all episodes of Wasteland on Hard or Hard.
All the same awaits you, it just becomes a little harder to play.

Exile: Conqueror
Complete all Wasteland episodes on Max difficulty.

Find all the caches in the Wasteland.
You need to find all the secrets in the add-on, the Guides will also help you, which, by the way, are also in Steam.

Exile: Achilles
Complete all episodes of Belphegor and the Wasteland on Superhero difficulty.
This is the hardest achievement of all, because you cannot die in Superhero mode. Achievement "Immortal", as it were, prepares you for this mode. If you die, you will start the whole mission all over again, so if you get this achievement, then only go after it, do not collect nanites and secrets, then spend much more time.

Chinese Farmer
Get access to all achievements.
This is the last achievement, it is obtained automatically after you have completed the previous ones, and it does not matter what kind of metal, silver or gold you got them (meaning 4 identical achievements differing in color and difficulty of execution), this achievement will still be counted. The achievement may not be added if you received the penultimate achievement not in the company, but in Survival.

These 4 achievements are exactly the same. You just need to destroy the Scarab. For high difficulties, the same method of 3 missiles (3 missiles in the sky and point to the scarab, by that time 4 missiles should roll back, but on 6 it should die just after keeping within 20 seconds, for another achievement).

These 4 achievements are exactly the same. You need to destroy a police car in 5 seconds, you can use several missiles at once, or with a launcher.

These 4 achievements are exactly the same. You need to destroy 2 police cars in 20 seconds. This should not be laborious if you have coped with the previous achievement.

These 4 achievements are exactly the same. You need to destroy 20 bots with the "Vacuum Cleaner". In fact, this achievement is hidden and you cannot understand how to accomplish it right away, but after reading it, I think you have already understood. If not, there are 2 vents in the "Crusher" mission, they do not attract you, but small bots may well be sucked in and crushed. First, there will appear about 15 such bots, later the wall will collapse from where the "Monkey" will run out, after killing which we go behind the wall, and more bots will attack you, lure them under the "Vacuum Cleaner" and your achievement.

These 4 achievements are exactly the same. You need to destroy the Scarab in 20 seconds, as I explained above, near the Hermit: Disinsection.

These 4 achievements are exactly the same. This achievement is also hidden. You need to lure Gorillas (Monkeys) under the presses switched on from the terminal, at any difficulty it is easy, the main thing is not to fall under the pressure yourself.

These 4 achievements are exactly the same. You need to destroy the last boss, like all previous ones, his weak points are highlighted, and Dr. Novak will constantly remind you that in order to remove the energy shield, you need the Overseer to eat nuclear elements. The big danger is not the boss himself, but his henchmen. On the 2nd floor of the arena, you will be shot by droids, and small bots, including suicides, will run across the field along with the boss, but in most cases the boss himself will devour them.

Thank you for your attention, like it if I helped you a little, because I would have done the same. Good luck with completing and earning achievements! If you have any questions, then I will definitely answer you as soon as I can. If you find errors or you have something to add, then write as well, I will consider your proposal and possibly add it to the manual.
