The Hardcore DX mod changes many aspects of the game in order to make it interesting to replay the original story again and again. The goal of this mod was always to make a lot of changes to the default game without modifying the maps and bring more action and combat. This mod includes several unique features that were not available in the default game such as multiplayer bots, alternative fire, new characters, new HUD, completely reworked weapons, augmentations, etc.
EXCELLENT modification for Deus Ex! It might be used as add-on to the original game, splendid mod!
