Their Finest Hour is the third expansion for Hearts of Iron III, and comes three years after the original game's release – further evidence of Paradox's com­mitment to building and growing their games well after the launch period, adding features and ideas requested by their active and involved international online community.

Features:

• Expanded espionage system with new and reworked missions, including new covert operations that can be performed on the map.
• New ‘battle plans’ mode where you can load historical plans, or draw your own and share with your allies in real-time in multiplayer games.
• New unique elite units for each major nation's army – Gurkhas, Rangers, Imperial Guards etc.
• Deeper naval invasions system including the development of specialized landing and assault crafts to improve the effectiveness of your assault.
• Leaders are now able to gain traits, and assigning them to duty is more important than ever with the new combat tactics system for battles.
• A new custom game mode for both single and multiplayer. You start with a clean slate and can instantly produce units, research technologies and affect political alignment before the game begins. This allows you to model interesting ‘what-if’ scenarios and speeds up the early years for those who would like to jump straight into the action with no slow build-up.
