Halo 2 does not count completed levels.
Hello everyone. Recently, my friend and I decided to complete Halo 2 on Legendary difficulty. We played the campaign with skulls (like a scarab and others). After completing the game, my friend got an achievement for completing it on Legendary difficulty, but I didn’t. I thought it was a delay on the part of the Xbox servers and decided to wait. But the achievement still didn’t come, so I decided to check the game’s statistics. It showed that I had completed 4 out of 13 levels. I replayed the entire campaign, but the statistics didn’t change. I noticed that I’ve completed 4 levels on the other difficulty levels as well. For the sake of experimentation, I re‑played a couple of levels on normal difficulty without skulls. BUT NOTHING HAS CHANGED. Has anyone encountered a similar problem, or am I the only one? I would be very grateful for any help.
