P-O-X is a handheld electronic game released by Hasbro in 2001. The game includes both single-player and multi-player modes and a 30-foot (9 m) wireless connection range.
P-O-X was introduced through a viral marketing scheme. Hasbro asked kids in Chicago schools, "playgrounds, skate parks and video arcades" who they thought the " coolest kid" was, until they found kids who felt they were "the coolest" themselves, and distributed free copies of the game to them.
P-O-X performed strongly enough in the Chicago market to convince executives major toy retailer Toys R' Us to come on board for a national launch, slated for September 23, 2001, planned to coincide with the start of the Christmas shopping season. Originally, a second phase of the launch had been planned for 9 additional cities in the United States beyond Chicago, but the launch schedule was pushed forward due to the strong support from Hasbro and Toys R' Us executives.
In a case of extreme poor timing, the terrorist attacks of 9/11 and subsequent 2001 anthrax attacks raised considerable doubts in the Toys R' Us executive team about the viability of launching a game that prominently featured Earth being attacked by malicious forces that took the form of bug-like viruses that 'infected' their targets. After some focus groups with parents indicated that they [the parents] were uncomfortable with their children playing a game that featured viruses and 'infection', the game was pulled from the market.
There are three different "types" of the game, each released as a differently colored console: the red Spino, green Cycro, and blue Plasmo.
Spino
"Spinoblast Violidae" Abilities: Power/Strength/Force Scientists first cataloged this species because the virulent and aggressive tendencies were so pronounced that they immediately struck out at every type of active or passive probe directed at them. The neuromuscular response was measured as a total output of all available energy. The Spino infectors all have powerful body parts, which do anything from doubling attack force to defeating an enemy in one blow.
Cycro
"Cycrocyte Violidae" Abilities: Speed/Agility/Stealth This species was harder to classify because its movement is so fast and agile it only appears as a visual smear on the scanners. A pheromone trace program and frame rate adjustment of the scanner allowed scientists to finally see them in detail. The Cycro are definitely fast, having some body parts that add extra strikes each battle phase, as well as some that stun another infector to allow for cumlative strikes.
Plasmo
"Plasmocid Violidae" Abilities: Deception/Defense/Camouflage The last species was hardest to classify. Originally, there were thought to be only 2 but background disturbances caused by a local battle brought them to our awareness. Natural camouflage adaptations have created a wonderfully complex defensive architecture that includes energy screens and active energy-refracting camouflage. The Plasmo act more on the defensive line than the offensive, with body parts that generate shields, deflect damage, and even one that cancels an opponent's first attack.
