About Hexen

Has rather unique difficulty levels, the number of enemies gets inflated as is to be expected, but better weapons are located later on, forcing you to fight with old and "less efficient" ones much longer. But since each character has only 4 weapons total, including the starting weapon, this isn't such a big thing but does prove additional challenge early on. There are some differences in encountered enemies between the characters, too (or they're randomized, but I haven't verified that). There are only two types of "ammo" (mana, really), where the second weapon consumes blue, third weapon green, and fourth weapon both. Unlike some other games of the time, magic was not simply dispensed from some magical weapons, but the character actually seemed to have proficiency in magical arts, as witnessed by the mage classes use of lightning and ice and cleric's use of fire. Hexen is also one of the first (if not the first) first-person games to implement jumping, as well as falling damage which is ignored in great many games even today.
