When I first saw this game (circa 1995 I guess), I was very impressed by the visuals in the first level, with all the monsters, medieval weapons and characters, the hall with stained glass windows and gargoyles, the castle wall and the cave and all that. Everything was in the right place for a dark fantasy setting. However, back then I did not complete even the first level and did not play again until recently. Yet the design of the first hub, the Seven Portals, after the intro level, turned out to be rather not to my liking, with those pretty abstract "guardian" levels and boring geometry of the hub itself. The game gets better in the second hub, Shadow Wood, where there's the forest, the swamp and the ancient ruins, although one of the levels, the Wasteland, is really enormous, and it is easy to get lost. The third hub gets back to the medieval castle theme, which is nice too. Kevin Schilder did an excellent soundtrack for this game, with a somewhat darker theme than in
Heretic, and many memorable tracks. The ambient sounds like the rattling of chains, wails, bird sounds etc. (depending on the situation) that play randomly also add to the game atmosphere.
Also noteworthy are the upgrades done to the
Doom engine in
Hexen (breakable glass, trees and other objects, horizontally moving sectors, the ability to jump among other things), and the hub system itself. The monsters this time are more into a "bestiary" type of theme, as opposed to
Heretic where there were more undead creatures (the undead only appear in the final hub). The enemies did not escape the palette swapping procedure, and each of the regular monsters seems to have a palette-swapped counterpart with a certain difference (e.g. an added ranged attack). Another nice feature is that each of the playable characters has a different style of play, as well as a unique set of weapons (including unique use of certain items like the flechette that works differently for each character).
It's a pity that the demo is
Unwinnable By Design, as the Guardian of Steel level is cut and thus the hub puzzle cannot be completed. I wonder why they did not put the entire first hub in the demo (or at least rewired the switches so that it could be completed without the Guardian of Steel level), seeing as there are five hubs in the full game. Cheats can still be used to get through the hub though.
