Explorer is one of the largest mods for Warband. Without changing the plot, it turns an RPG with strategy elements into a full-fledged RPG with a huge open world to explore. The general map of Calradia is gone - now the player moves through a full-fledged world, like in any other RPG.

This affects many details of the gameplay - if previously soldiers could be hired in dozens, now you need to negotiate separately with every. Everyone has their own name and their own skills that can be used by the squad. Mercenaries also play the role of successors - if the player character dies, one of the mercenaries on his team will come under the player's control.
