The core of this mission involves activating three Remnant monoliths scattered across Eos. Each monolith site will be guarded by Remnant constructs. You'll need to defeat these enemies and then solve a Remnant decryption puzzle to activate the monolith. These puzzles involve matching symbols in a grid; if you struggle, you can use a 'Remnant Decryption Key' to bypass them. Activating all three monoliths will significantly reduce the radiation levels on Eos, making it habitable.
