Calradian Knights Mod is an ambitious RPG game that will allow you to create and develop a powerful army of legendary warriors. The idea is that you play a legendary leader, or leader of an army. Your soldiers will battle in a 3D environment and they can be developed by collecting items that can increase the attributes of your troops. The item gathering is made easier through the game, as every time you complete a mission, you’ll earn a reward and a portion of the money will be stored for the next mission.

Creating an army is also easier than it seems: you’ll just need a weapon, an accessory, a helmet, and armor.
