The uncut version of Tom Six’s “The Human Centipede 2:Full Sequence” is currently available on SundanceNOW before the film is officially released on DVD next Tuesday (makes for a perfect Valentine’s Day gift, if your significant other loves shock and gore).

In an effort to further promote the film, SundanceNOW is giving ShockYa four access codes to give away to four lucky winners. These codes are vouchers to watch the film free on SundanceNOW. Also, the four winners will receive a copy of the movie poster.

To win the codes, ShockYa will hold a Twitter giveaway. Here are the rules:

First, follow us @ShockYa. Make sure to @mention us the phrase, “I want a Human Centipede 2 code! Follow @Shockya and Retweet This” You have until Friday, Feb. 15 to tweet us, and only tweet this once per day. We will pick the four winners at random, so make sure to check your twitter accounts to see if we have notified you of winning!

Here’s the official synopsis of “The Human Centipede 2: Full Sequence”:

“The iconic Dr. Heiter has inspired a real-life protege, the sickly, disturbed security guard Martin — who takes his gory inspiration from the original film to horrific new extremes…and one-ups the doctor with his pièce de résistance, one of the actresses from THE HUMAN CENTIPEDE (FIRST SEQUENCE), Ashlynn Yennie.”
