Ghostfire Games' Rage of the Gladiator is on the way to WiiWare, and now we have word of another first-person, MotionPlus-enhanced WiiWare game involving ghosts: Ghost Slayer, by Gevo Entertainment.
Ghost Slayer uses the Wiimote (with optional MotionPlus) to simulate a sword as you fight howling, glowing ghouls in first person. According to the backstory, ghosts (led by a Ghost Queen) are pouring out of a dry well, and it's up to you, as a Ghost Slayer, to hit them a bunch of times with your sword!
The North American release date is currently TBA. In the meantime, you can be creeped the hell out by the trailer after the break.
