Undead Must Die.

A full conversion mod that attempts to add an Undead Horde mode to the game. This is a complete conversion mod that removes quests from the game and forces you to appear in the Guild of Heroes. Each map is filled with undead enemies and various traps. Make your way through each level, defeating the hordes of the undead in any way you like. When you're done with a level, simply return to the Guild of Heroes, revive yourself, and move on to the next level. There are traps placed throughout the maps to help soften up the horde and make things easier for you, just remember that enemies killed by traps do not give you experience - unless you manage to harm them first.
