so you draw a line of the enemies you want to hit, and then the character does the slash with the sword, motion+ not even needed since it relies by the looks of it on the IR sensor.
This game reminds me of 2 other games, the 1st that on rails Dragon quest game and the 2nd that dynasty worrier game, it's not on rails but it's the sword play mechanic which reminds me of those two games.
I have to say, it looks like a tedious mess, I guess we'll see how this game turns out once it's released.
