I have amazing news! System Shock 1 has been brought back in all its glory by Looking Glass Studios, the same team that brought back other classics such as Harvester, I Have No Mouth, and I Must Scream, and of course, System Shock 2.
When you buy it you'll have access to both an "Enhanced Edition" and a "Classic Edition" of the game, as well as a ton of goodies including the soundtrack in three different formats and the full original strategy guide!
Check it out on GOG.com here! For those of you that want a Steam version no word has been said on it but you can probably expect it soon!
