I got this for Christmas in the late 1990s in the big box PC packaging. I found this game to be exceptionally atmospheric, and although it's easy to complete if you know how, I still enjoyed spending hours exploring the large complex and riding the tram from building to building. It had a unique feature in the VOS terminals which was an in-game operating system you need to use to program automated defences. I would love to add this to my collection, as I'm sure many others would too.
