In a recent press release, Ubisoft announced that their upcoming title, Assassin's Creed: Revelations, is getting 3D support.
The lovely addition doesn't prevent gamers without 3DTVs from enjoying the lush experience. Non-3DTV owners will be able to get the 3D experience from having TriOviz Inficolor™ glasses. If you do have a 3DTV, then never fear as that is also supported in the game from top-to-bottom.
So there you have it: the next AC will allow you to experience the assassinations and blood in 3D. Assassin's Creed: Revelations is slated for a November 15, 2011 release and that's when you'll get the bloody experience.
