Here’s a trailer for Defend Your Castle, which will be one of the first WiiWare games available for download (not to be confused with the Virtual Console games). It was originally available as a Flash game but it’s taken on an overhauled look, 4-player multiplayer, and enhanced physics and particle effects. The developer, XGen Studios, says “Defend Your Castle has been re-created from the ground up to utilize the unique capabilities of the Nintendo Wii and Wii Remote,” so it’s not a port or a remake.

It’ll be available on May 12 for 500 Wii points.
