alright this is really starting to drive me insane.... all these clues, the power boxes and fusebox in conjunction with the writing on the walls plus the hints at something very large outside the building ( i refuse to believe those large growls and the collapsing ceiling is simply the crawlers, they are too small for those kind of decibels and damage).
i've survived up to level 30 solo and it doesnt matter how good you are it always adds up to a lack of ammo, ive been trying different combinations of breaking the powerboxes before or after the power is turned on and every which way i try spells frustration, we really need to get more people in on all of this, too many people are oblivious to how deep this all seems to go... and i swear if treyarch is just messin with us im gonna be so pissed lol
