Shanblue Interactive has confirmed that its WiiWare action title Vampire Crystals will launch this month in North America. The date to look out for is December 20th, with a European release following on January 3rd, 2013.

The top-down shooter has been in development for quite a while - we first reported on it back in April. The game is also coming to the 3DS eShop at some point next year.

It's certainly looking impressive - you can check out the official trailer and tutorial videos below.
