After several delays it's "Finally" been released. If you own all three, you get it free, but it doesn't just show up in your games list or inventory. No, you have to go to the neocore redemption page
and log in with your steam account. Apparently, you must have your account set to public for the redemption. I don't have any impressions yet since, even though I have all three installed, it's still downloading 12.9 GB's.
<insert Van Helsing redemption joke here.
