Gametrailers today showed off it's first Wiiware game trailer, of the upcoming title: Defend Your Castle, In it, the movie shows multiplayer co-op, as well as the addictive looking single player where you are a commander of your castle and you control an invisible floating hand where you try to fight off an ever increasing amount of enemy armies, with conversion and physics based gameplay.
The game is expected to launch in USA on May 12th, this year. Sadly the feedback on the item has been poor; the video only scoring a low rating of 7 average, hopefully Wiiware will pull through however and deliver a whole community's worth of triple A quality games.
Update: Here's the trailer off Youtube!
