Hey folks. Been going for 100% completion and finally got around to the Halo 2 skulls on Legendary. Already grabbed the Envy and Assassin skulls and the achievemnts popped for Xbox but not for Steam. I’m going to continue grabbing them in the hopes that they will pop randomly a little later, will post updates.
Got the achievements to pop. Restarted pc and played some multiplayer and they randomly popped on the main menu after a game.
