The first trailer for Castlevania Mirror of Fate has been released online. This includes a look at the game's cutscenes and a brief teaser of the gameplay. It's a 3DS game said to take elements from the non-linear Metroidvania style of previous handheld Castlevania games in the recent past. The game itself however continues as a sequel to the Lords of Shadow reboot instead of being part of the original Castlevania canon. While the game is a sidescroller at heart, the visuals are built with polygons using a cel shaded style. So the game has a rather striking art style.
Mirror of Fate does not have a release date yet, so keep an eye out for upcoming news about the game. More info may become available on the game during this week at E3.
