I've noticed some discrepancies with the achievements in their descriptions. It seems Xbox uses slightly different ones from both Steam and Playstation. I haven't checked all the main game ones, but we seem to have gone with the Steam/Playstation descriptions on the few I did, it's the last two DLCs where they're off.
Another Brother Falls
Xbox - Complete "Another Brother Falls".
Steam/Playstation - You survived the drive into Sinclair Parish.
Creature of Habit
Xbox - Complete "Creature of Habit".
Steam/Playstation - You investigated the scene.
Seeing as we went with the Steam/Playstation descriptions on the main game, I think we should follow suit with the DLCs.
I've noticed that too, and I'm also thinking we should change them. I think the reason we ended up with the Xbox descriptions is the DLC achievement pages were created before the game was released, when the other ones weren't yet available.
I finally downloaded all the Xbox achievement images and got them renamed. I'llbe uploading them here soon and adding them to the achievement pages. As far as their resolution, I think the standard ones found on the achievement site will be fine. If there are some we want to add to other pages and there's a larger version of it, we can replace them then.
