Since Generals Zero Hour is not available in Steam, my 2nd-place (or app) to-go is Lutris. Checking if C&C Generals Zero Hour is Available in Lutris My gaming PC's system information shown in neofetch. The machine I will be installing the game to is my Pop!_OS PC I regularly use in my Linux gaming journey. This guide will be a walkthrough on how to install Generals Zero Hour in a Linux machine. However, I have an idea that installing Generals Zero Hour is not as straightforward as installing a game from Steam. This makes me want to play it myself on my PC. Recently, I found myself watching Generals Zero Hour gameplays on YouTube.
