It's available in the store now for $12.99. I just bought it though it isn't registering for me even after reactivating the license half a dozen times and restarting HL Classic the same amount.
Starting skills aren't there and starting with 15 skill points instead of 12 was what tipped me off that something wasn't right.
There's no option to click "SWADE" and there isn't any indication that the data files were even added to my account with the exception of the data files product site where it says I own the SWADE files for HL.
So disappointing.
