![]() ![]() With listing the retail value of just a 2013 SRT Viper at somewhere between a cool $97,395 - $120,395, one could only imagine the value of this one-of-a-kind car. This is truly an exclusive that GameStop was lucky to score. Sadly, if you don't have a GameStop account and have no points, you can only enter zero times. It's set up in an old fashioned new-tractor-at-the-county-fair style lottery, only instead of dollars the currency used is "PowerUp Rewards Points." 1 entry costs 200 points, 7 entries costs 1,000 points and 15 entries costs 2,000 points. (For what it's worth, I recommend listening to Eddie Murphy's "Party All The Time" from Los Santo's classic rock station to the future winner.)įor a chance at being that one person, you will have to head over to the GameStop website and enter. ![]() Only one person will ever have the privilege of driving around while perhaps listening to some of the tracks slated to be on Los Santos' radio stations in a Banshee they can actually call their own. ![]() You can't buy it, you can't rent it, and you certainly can't steal a bumble-bee colored one for Brucie Kibbutz. To reiterate, this car can be yours - but before you get all excited, you should be aware that the chance of it being yours is insanely slim, as this car is a one-of-a-kind. Allegedly, original in-game textures were used as a template for a completely customized car cockpit, with such specific detail that even the upholstered seats are embroidered with a Banshee logo and insignia. Make no mistake, using a real car as a basis and only tweaking certain details is the pattern with most cars from Grand Theft Auto, but don't be fooled into thinking Rockstar just bought a Viper and slapped a Banshee sticker on it. More accurately, it is a converted Dodge Viper made to replicate the appearance of the Banshee, which closely resembled a Viper in the first place, just with notes of a Stealth, Camaro and Firebird mixed in. Needless to say, it's gone a long way since its first appearance when it looked like this:įurthermore, it's probably easily come further than any other car there has ever been in the GTA universe because, well, it's a real car now. They also may remember it as the car you can sell for a measly $800 in scrap metal in GTA Chinatown Wars. Since then, it has appeared in every other GTA game. Keen-eyed gamers may remember it from its most recent iteration as the car you drive when you chase the back-stabbing garbageman Luca Silvestri to his death in GTA IV and as the car Lenny Petrovic is driving before you riddle him with bullets. With these molds each panel was laid out by hand to create an entirely new exterior resulting in a screen accurate reproduction of the Banshee.Īs they say, the reason it might seem familiar is because of its prominent appearance in the opening of GTA III. Utilizing state-of-the-art fabrication technologies, molds for the exterior were cut and machined piece-by-piece for the high performance base vehicle. Significant work went into creating this real world version of the 2013 model featured in Grand Theft Auto V. With its aggressive, oversized styling and powerful engine, it became a mainstay as one of the most sought after high-performance rides from coast to coast - from Liberty City all the way to Los Santos. This shiny, shiny car is the 'GTA Bravado Banshee' and, technically, it could be yours.Įver since its debut as the getaway car in the opening moments of Grand Theft Auto III, the Bravado Banshee has been a symbol of the ultimate American sports car.

From its debut season “Murder House” to the fan-favorite “Coven” to the most recent “Double Feature,” I have seen it all. And yet, over the past five years, I have found myself shamelessly entranced by “American Horror Story” (AHS). I flinch at every jump scare and end up watching most of it through my fingers. The first was Beauregard Langdon.I cannot stand horror movies. He is the second known character to be smothered to death with a pillow.Luke soon wakes up from his coma and confronts his mom, who smothers him to death with a pillow. Things take a dark turn, however, when Luke begins to communicate his knowledge of Joan murdering his father by putting bees in his car and triggering a fatal allergic reaction after catching him receiving fellatio from a mistress. After entering the room anyways, the comatose Luke manages to talk to Nan and she is able to verify to Joan that she is able to read Luke's mind. Īt the hospital, Nan tells Zoe and Madison that Joan refuses to let her see Luke. When the paramedics take him to the hospital, she follows him. Nan tells him to not leave her, that she is his Supreme. Luke dives in front of them to protect Nan and is hit. Ramsey threatens them but is interrupted when a rifle sight appears on her and she is hit twice. Luke tells her they are leaving and she cannot stop them. Then they run into his mother, calling 911 to report an armed intruder. She finds Luke bound and gagged in a closet.Īt the Ramsey's, Nan and Luke head for the door. She mixes up an Ajax enema and forces him to strip.Īfter Nan telepathically hears Luke's distressed cries, Nan runs to his house. She says he's unclean from the inside out. He insists that they saved him, but she wants him to repent of what she perceives as sin. Luke's mother scolds him for going over to the Academy, saying the girls are using dark magic. Nan slips out the door and aids Luke to take refuge inside Cordelia's car. Zoe charges to the aid of an exposed Nan and Luke with a chainsaw and quickly dispatches many of the intruders. Luke and Nan manage to escape to safety. The day after, Luke is asleep in Nan's bed. Luke tries to flee for safety but is struck down. While Luke walks among the dormant zombies, Marie commands them to begin. In Cornrow City, Marie Laveau is levitating on the veve, the ritual symbol drawn on the floor. The girls are terrified, but Luke thinks it is all a prank. He, the witches, and Delphine are trapped inside. Nan is delighted to see him, but zombies soon attack the house. On Halloween evening, Luke visits the academy, bearing cookies to repay the cake Nan brought him. He ignores Madison's provocative attitude, and seems more interested in Nan. Luke welcomes them, and decides to eat the cake with the girls. Later, Nan is accompanied by Madison to the Ramsey house, bringing a cake to welcome them into the neighborhood. From one of the balconies of the Miss Robichaux's Academy, Queenie, Nan and Madison watch as their belongings are taken into the house. Luke Ramsey moves in next door with his mother Joan. He had brown hair, worn in a side part, a muscular chest, and blue eyes. ![]() He enjoyed Nan's company, but seemed uninterested in Madison's sexual advances. Raised by a Christian fundamentalist mother, he did not know much about the world around him, especially that of popular culture, which his abusive mother forbade from consuming. Luke was a well-mannered and polite boy, who tended to be shy and mild-mannered. Sheltered his whole life, Luke finds himself torn between loyalty to his religious mother and the undiscovered mysteries that lie just beyond his own front door. Young, handsome and new to the neighborhood, Luke Ramsey quickly attracts the attention of the girls at Miss Robichaux's Academy. ![]() ![]() ![]() This space is usually left for additional charges, discounts and other details that might change the total amount of the invoice.
