As of this week, we have a wiki page for System Failure and other Portal/Half-Life based projects made by Spekktrum Studio.
There isn't much to see yet, as it was just created, but those who are interested can feel free to check it out as it might have some information not available elsewhere. Anyone is also freely available to edit and create pages for the wiki, just keep in mind that any inaccurate information or vandalizing will be reversed.
You can check out the wiki, here:
