This game is not for people who have only played DOOM-cubed. This game is for people who played ClassicDOOM on DOS. Released during the same era of gaming, rather than being stranded on Mars with only a space-pistol, you're a Heretic, cast out by your fellow man for daring to see the enemy for what they truly are. After D'Sparil's armies wipe out your town, you creep back in with only a Wand, helltbent on revenge. Like ClassicDOOM, this game originally came packed with three episodes, complete with frightening enemies, awesome weaponry, and amazing powerups. Unlike ClassicDOOM, you also had the ability to look up and down and even fly. Shadow of the Serpent Riders added two additional episodes, but as far as I can recall, no new enemies, weapons, or powerups; just new levels.
The game itself is froxen in time; the graphics have not been updated and I doubt anyone will attempt to do so. As such, it is somewhat difficult to see in the distance on the better-developed machines of today. However, this is my only gripe, and there's nothing that can really be done about it. I bought this pack for one reason and one reason only: to return to my childhood. Nostalgia. To remind myself why I got into gaming in the first place. And there is absolutely nothing wrong with that.
People looking for "new and exiciting machanics" will be sorely disappointed. But if you remember the 90s, and ClassicDOOM, and Wolfenstein 3D, you need this in your collection.
