Raven Software developed Heretic, its sequel Hexen, and Hexen 2, and id published them in the '90s. In some ways, they were more innovative, fun, and original than id's more well-known first-person shooters. You could choose a character class, and Hexen 2 introduced destructible environments and mounted weapons.
Hexen: Edge of Chaos is a mod for Doom 3 and will be completely free to play. Looking at the screenshots for this game makes me want to play Lo Wang is Shadow Warrior using the Half Life 2 engine. Can someone get to work on that? Thanks!
