Discover all 30 AltarsWhile the achievement description states to find “all 30”, there are actually far more than 30 altars present in BIOMUTANT. You only need to find ANY 30. They are called Psyonic Shrines in-game.
Each enemy Outposts has an Altar in it, usually to the left or right after going through the main entrance. These are the first 18 locations easily visible on the world map and have fast travel points, so they are very fast to find. Then the remaining 12 are open world ones.
Follow through this video guide by PowerPyx to spot all of them.
