Ok, I am new to gog and I am a bit cunfused about the content of the Blood game (have bought a few games but only played Tyrian!).

I see that we have the base game and that we can launch the Cryptic Passagem form start menu. Is that all Blood official content? What about the Plasma Pak (or somethuing like that)?

Plasma Pak added Post Mortem episode and few new enemies (blue Elite with Tesla Cannon, green Acolyte throwing bundle of dynamite, Fire and Acid pods, and Priests transforming into Beast). Weapons in Plasma Pak have mostly new alternate fire modes. Most definite version was released later as One Unit Whole Blood with Plasma Pak integrated into Blood1 along with copy of Cryptic Passage. Note that due to engine alterations, intro movies (monolith and such won't play even if in correct folders and game will straight load demo with main menu but that's all.

Ok. Thank you for the clarifications.
