- Key Unlockable: The “MYTHIC” Achievement for completing the game on LASO
The recent developer livestream showcased a variety of gameplay options, including split-screen co-op, a four-player Remix lobby, and a deep dive into the modifiers that define the LASO experience. Completionists aiming for the "MYTHIC" achievement should be aware that if any member of their Fireteam has Difficulty Modifiers enabled, the achievement will not unlock.
