I'm surprised. Usually games make sure to take over all user input entirely. That HalfLife is letting some fall through is odd.
Anyway, QS itself does not provide a means to do this. But you could just paste the following two lines into AppleScript Editor, save the script somewhere that QS will find it (~/Library/Scripts is a good choice), and then run it via QS as the way you launch Steam. tell application "Steam" to activate tell application "Quicksilver" to quit You'll have to restart Quicksilver when you are done playing.
