The new levels alone are quite good, and do a wonderful job of adding onto a game that was wonderful to begin with. I'd compare it to the Plutonium Pack for Duke Nukem, although a few new weapons and enemies were made available there. The Cryptic Passage levels were created with the care that was obviously taken with the originals. If you are a Blood fan, and would like to play some more of the game, then Cryptic Passage is for you. It's even bargain priced so you do not have to spend a fortune getting your fix. If you are looking for new enemies and weapons, you won't find them here, but you will find ten large, new, challenging levels that continue Blood in it's original tradition. Bottom Line: A continuation of Blood that follows the tradition of the original quite closely. No new weapons or enemies. Level design is almost as good as the original. Contains nine new levels, one secret level, and four Bloodbath levels.
