Hexen

Hexen is the sequel to Heretic, with a few major differences. There are three different types of characters you could play (with pros and cons for each), there are plenty more artifacts, and some of the artifacts are used differently. Hexen is also different from Heretic and Doom in that you can look up and down, and you get hurt when you fall a long distance. To gradually look up, press "Delete". To gradually look down, press "Page Down". To return to normal viewing range, press "End."
