It's short but pretty intense. Level design has improved and there are some more sophisticated scripted events and tricks (e.g. in one level there is a button that gets angry and kills you if you press it too many times). Difficulty increases as well - more monsters, combined with an increased rate of monster spawning through the maps. Three hubs, each with its own secret level (yay), and several boss encounters. It's worth trying.

Heretic II feels pretty different - not only because of the 3rd person view, but also in terms of overall gameplay. It's not a pure FPS, there are some adventure elements as well. And some of the terrain navigation parts feel like Tomb Raider.
