Atlus’ first high-definition title is a little game that goes by the name of Catherine. In development at team Persona, the game is currently eighty percent complete and scheduled for a winter 2010 release.

Today, two days after the game’s announcement, the debut trailer – featuring both anime and gameplay scenes – has been released.

You’ll see Vincent in polka dot boxers and Catherine trying to seduce him in his nightmares. When Catherine first steps in halfway through the trailer, you’ll hear her tell Vincent to do whatever it is he desires with her. She’s a nympho, if you didn’t know. I’m not sure why there are rams there, though.

See the trailer below. Additionally, low-res images of the game can be seen at Famitsu.
