Disabling this option is limited to a certain extent. To hide it, you will have to play in Level 1 mode, which is the same as "Hardcore Mode"3 in previous installments. To do this, you will have to start by selecting Private Match in the main menu of the game > select "Create private match" > then a game mode > go to Game Settings > Game Rules > Game at the top, where you will find a switch for" Level 1 mode"
Turn on the Toggle and you're done
This will disable the HUD elements in the match, except for a few.
It will also enable friendly fire, and you will have a much lower HP which you can use to take some clean screenshots of the game.
This is all you need to know about how to hide HUD in Modern Warfare 2, so we hope we've been as helpful as possible for you to disable this tool whenever you want.
