Here are scans of all the official strategy guides I could find. I have also linked my collection of other DOS game strategy guides at the bottom.

System Shock I.C.E. Breaker - Origin Systems

System Shock I.C.E. Breaker (Maps) - Origin Systems


Other DOS strategy guides

Thanks, I guess. But after a quick comparison between these files and the versions included with the GOG version of the game as extras, I don't see any differences. Am I missing something?

Ah, sorry, I didn't check to see if the strategy guides were included with the GOG release. I went through all of my strategy guides and picked out the DOS ones then made a thread for each. In all other cases, as far as I'm aware, the guides weren't included as they are normally Brady or Origin guides. Feel free to check out the other guides linked in the OP.
