Summer Sales on Steam has begun! 20% off!

Ladies and gentlemen, your attention, please.
This year, from June 23 to July 7, you can get "Diplomacy is not an option" with a 20% discount.
It is time to put your strategist skills to the ultimate test. Become a medieval feudal lord, forced to hold the defense against countless hostile hordes. Gather resources, manage the economy, develop your city, and don't forget about your army. Because the enemy will come to destroy everything you've built for he knows no mercy. Your task is to survive at all costs.
Thank you for your time. Enjoy the Summer Sales!
