Bloodmasque is a game where you can transplant your face onto a vampire hunter and embark on an adventure that plays out like a Dracula version of Infinity Blade.

Square Enix has confirmed that the game has been downloaded over 500,000 times. Normally Bloodmasque costs $6.99, but right now it’s free until December 16.

To make things festive, Square Enix is also holding a holiday event in game, where you can obtain a Christmas themed sword and a Santa suit by defeating Rudolf the Red (assuming this is a vampire?), or a Sleigh bell Skirt from defeating Holly Mistletoe.
