Speed Kills, for example, use the Nunchuck to initiate [the attack], and timed strikes with the Remote in order to complete the multi-hit combos...The 'Dagger Plant' move by the Prince has always been a favorite of mine and is now made all the more intuitive and satisfying by the fact that you must strike (in a stabbing fashion) with the Remote in order to plant your dagger in the wall. When using the Dark Prince's Chain Swing ability, too, the motion control is used -- for each swing the Dark Prince does, the player must strike with the Nunchuck.

Despite the fact that the titles share the same name, the PSP version features some unique levels and features (such as a multiplayer "race" mode).

I'm really hoping we'll be able to attract both! Fans that have already played The Two Thrones should play Rival Swords because, quite simply, no one has ever played the Prince like this before. I believe very strongly that the controls have added a new level of depth to the game that all fans of the franchise should experience. Of course, people who didn't play The Two Thrones will find Rival Swords an exciting action-adventure game with gorgeous environments to explore and perilous combat to master.
