Battle Realms: Winter of the Wolf Cheats and Tips

You can't do this in the vanilla/unmodded version of the game. You can use mods and trainers but it will take several steps that we won't be discussing here. There are still old forums discussing methods how to achieve this, kindly use Google to find them. Take note that using mods/trainers/cheats may corrupt or ruin your game if done incorrectly so proceed at your discretion and risk.
