add a category where you have to complete every objective in main game, time starts on first movement, ends on the final objective completed

You mean Area 51 personnel? Sure

yes, just the objectives in the menu when you are in classic mode

got a 17:10 in this category, waiting for the category to be added in the first place :P

you will need to submit a request with video proof if you want to be added to the leaderboard.
