Basically, It will be a machine created by a researcher from a university who attempted to create a machine allowing human beings to cross dimensions and reach the "Gods" and gain there power and wisdom. The foundation catches a whim of this Idea, and surrounds him in his home and the surrounding suburb (with help from police, they told the police he was carrying an incendiary device). He then turns on the machine which warps inhabitants and objects from alternate dimensions and times into the suburb (he did not have enough time to power it up enough for it to be anywhere near large enough to encompass the planet). Hordes of extradimensional creatures appear everywhere (mainly predators, with some sentients) and start to basically tear the place up. In order to contain the outbreak, the foundation nukes the suburb. As an excuse, they stage it as "a deadly virus that creates hideous illusions and ultimately death, and that they had no choice but to use a nuke to stop the spread. It was used as a weapon by a terrorist organisation"
I'm still deciding what features need adding and/or removing. But, will it be good? Is it original?
