Open your Steam library and find Ace of Spades as shown in the image below:

Right click on the game and select "Delete Local Content", press "Delete". The game should now uninstall, it should take less then a minute as it is small.

The game's status should be "Not installed"

Right click on the now uninstalled game and click "Set categories", click the checkbox saying "Hide this game in my library". The game should now be hidden from your library.



Additionally, open Ace of Spade's store page and leave a negative review.

Thanks to everyone who read this guide, I hope this helps everyone out there get better at the game. Don't forget to leave it a like and a comment!
Ps. Do not buy the DLC, this will only worsen your aim and it'll probably get added to the game for free anyway.
