Today, Gamespot has quietly unveiled that The Conduit will utilize WiiMotionPlus add-on. Heres the quote:
"Using the Wii Remote and specific weapons, you can shoot around corners by twisting the remote to get people that are hiding out of sight and some weapons can be guided using the cursor like a missile. High Voltage does plan to support Wii Motion Plus add-on so we will have to see later how that will work."
Sorry for using the incorrect link, but the same article was released without announcing WiiMotionPlus. Simply go to the first article.
