I just found that Silent Storm and Silent Storm Sentinals are packaged together as a gold edition and dirt cheap on gog.com. These are some great games in the TBT genre. They are pretty dated but still well worth the money to play around with between releases. I am still having a hard time playing Xeno more than a few missions at a time due to the AI, but I am betting when it is all complete you won't be able to pry me away. So, just wanted to share my find.
