Instructions
Press "New Game" in Feudalism's main menu and choose a character. Right click before you press "Play." After a few moments, you will begin the game with a level 50 hero with a huge gold stockpile.
Place one of your units in the last reserve slot once you have an army of at least ten soldiers. Move the unit to any location near the rest of your soldiers. Repeat this process as many times as you like. Save and exit the game, then return to it. You will find a group of new soldiers whom you can either enlist to fight for you or sell back to the barracks for easy gold.
Select a ranged weapon such as a bow and arrow for your secondary weapon slot and put a cheap melee weapon that you don't mind losing in the the primary slot (a club is a good option). Get rid of the melee weapon, then drop the ranged weapon as well. This will cause an extra ranged weapon to spawn. Repeat this process and sell the new ranged weapon each time to make killer bank.
