I'll have to rely on my friend's knife collection for self defense for tomorrows... activities.
That, unfortunately, will not help us when the fire begins.
Fire will literally rain down from the sky. The bio-mass will rise up from the sewers and continue to grow with every human it swallows. It won't be long before it is strong enough to infect humans, giving them full control of the bio-mass inside them, while simultaneously controlling the humans actions, much like a zombie. Meanwhile, an actual zombie virus will spread rapidly through the city. Spiders will become noticeably more aggressive towards humans. They will be genetically altered by the second, until they grow to biblical sizes, literally devouring everything in their path. We must survive for as long as we can before the government nukes our asses. Wish us luck.
