Just like in the game, the newly launched Catherine website lets you send text messages to Catherine. You'll have to send the right text to unlock goodies like hidden artwork and wallpapers. I went the flirty route, like I'd normally do in real life. Here's my reply to Catherine asking if I kept the game's launch day open:
God, I'm such a stud.
The site says that you'll need to check back daily to get the responses for your texts. Very cool.
On the same virtual phone you'll find wallpapers and avatars. The rest of the site has screenshots, video and more game information to get you ready for your July 26th 'date' with Catherine. I'm ready.
