SLASHER REMIX You remember the nightmares, don’t you? A masked psychopath with a chainsaw, a bladed hand, alone in a cabin in the woods. You tried to scream but nothing came out. No one could help you. Well, we’re sorry to say you don’t outgrow the fears of the slasher films of yesteryear... you just hide them away. This year, we’re resurrecting those exact memories, twisting the characters that haunted you the most, and making you face them as you try to make it out of the cabin in one piece. Will you overcome your nightmares this time around,? There is only one way to find out...

UNDEAD: ABOMINATIONS The rumors and conspiracy theories are true. You are sure of it. You’ve heard about the subterranean labs deep beneath the hum drum surface of River North—the experiments, the mutations and the discarded bodies that are buried there far below the businesses and condos we see today. But there is no rest for the “Undead”; quite the contrary. Many of the subjects were experimented on and survived the now-abandoned lab and the mutations continued under the watchful eye of guards and quasi-scientists... until something unthinkable emerged from the bowels of the earth... an “Abomination”. Indeed, the walking corpses that now terrorize the deep dark passageways and nooks of the underground have begun to find their way out. Will your group make it through unscathed or will the Undead: Abominations take some of you for their ranks?

CURSED: THE RITUAL The hamlet of Blackmoor has been overtaken by werewolves, which emerged from the nearby cemetery’s cavernous crypts and tombs a year ago. But the mystery remains as to how the town’s citizens are taken into this dark wolven tribe. Cursed: The Ritual takes you back to before the “Feral Moon” awoke these ravenous creatures, when the living and the undead were revived by the act of necromancy of a local “bokor,” a sorcerer or witch. That’s right... VOODOO! These undead canine beasts can be traced back to Haitian roots and their red eyes are a sign the evil has taken possession—as goes the folklore. A zombie remains under the control of the bokor as a personal slave, having no will of its own, so you must be strong as you pass through these unhallowed grounds. Can you resist the call of the voodoo priestesses or will you be called into the order of the ritualistic, cursed werewolves like so many before you?
