It’s a game that’s been resilient in its popularity, even after all these years, and as usual you can thank the mod community for that. There are many mods that bring Generals and its lone expansion, Zero Hour, alive in new and exciting ways.
C&C World War II is a mod for C&C Generals: Zero Hour which reskins the game to bring it into a WW2 setting, and is mainly focused on multiplayer. It’s described by the mod team as the “Russian” answer to a similar mod made by a German team called C&C Generals Blitzkrieg. You can play as the Allied Army (joint contingent of U.S. and UK), USSR, Germany, or Japan, and units are separated by ‘tiers’ that cover the year various hardware was brought into action.
