Cryptic Passage is the first of two expansion packs for Blood. Unlike the Plasma Pak, the expansion was developed by the third party Sunstorm Interactive and published by WizardWorks Software, therefore it does not contain any bug fixes or new features. However, it does contain a new episode containing ten single-player maps, and four new BloodBath maps. Despite not being developed by its rights holders, Cryptic Passage is still considered part of the offical Blood canon, though none of its story elements show up in subsequent games. It is set sometime shortly after Blood (with hints like the opera house showing it to be in the 1930s).
 New Episode: Cryptic Passage

He must find the scroll and take out everyone responsible for interrupting his journey.

Episode 5: Cryptic Passage
Caleb arrives at some docks (E5M1: Boat Docks), which opens onto a large cave, a cabin and a lighthouse. Everything is overrun by the Cabal, and Caleb must fight his way through to a city (E5M2: Old Opera House), where he enters a large opera house, which apparently is showing the "The Phantasm of the Opera". Without losing any time, Caleb goes out into a back alley and finds a library located in the midst of a forest (E5M3: Gothic Library). He escapes the minions of the Cabal after recovering all the keys required to access the Lost Monastery (E5M4: Lost Monastery). Once home to the "Holy Order of Carpathia", strange rituals are taking place, and Caleb ends them swiftly with his own brand of justice. The Carpathian Queen, a passing steamboat, provides escape (E5M5: Steamboat), but since the Cabal owns the ship, and uses it to ship its own brand of cargo, it proves less than a gentle ride. Caleb grounds the ship and finds himself in a graveyard (E5M6: Graveyard) whose relatively empty surface hides some crowded underground catacombs. If Caleb finds the proper entrance, he can reach a gloomy swamp (E5M10: Boggy Creek), where it is said Death itself drives a boat searching for unwary travelers and lost souls. Otherwise, Caleb enters a secret crypt leading to the mountains proper (E5M7: Mountain Pass), where large gorges, sheer cliffs and ghosts are at every turn. Caleb moves through the mountains and into a mine (E5M8: Abysmal Mine), a dark place infested with Cabal. However, it provides access to the hidden castle where an ancient path to the "otherworld" lies (E5M9: Castle). Caleb ascends the stairs, and finds the antechamber of the scroll, as well as its guardian, the Lord of All Nightmares which proves to be two Cerberi.
