For those people intimately familiar with the series, there are a few additions that stand out the most. These are almost all carried over from the Warlords: Battlecry series of real-time strategy games. In Battlecry, one created a persistent warlord in a typical RPG fashion. That hero was there to stay, whether the player won or lost a battle. Interestingly, one could even play skirmish games on random maps and use the experience gained to boost this character. Warlords IV also implements this feature. One can start a quick game on a pre-made or random map and build up their main character stats. This is especially useful for tackling some of the tougher campaign missions. Up to three units can also be carried over from game to game, allowing one to nurture a red dragon through the ranks or always have his or her favorite orc by their side.
