Armagedon?

Andrew searched the corpse's former possesions (at least the ones that were clean enough and not covered in vile blood or flesh leftovers), to find some ammunition for his trusty gun, a piece of bulletproof armor which he could use, and a very old and seemingly-broken tape recorder, like the one reporters use to interview someone.
He presses the rewind button to check if it works, and when, to his pleasure, he found it was alright, he let it like that for a bit, then pressed play.



*sounds, probably bad quality of the tape or data that has been corroded*
"Day 6. i have no idea what these things are. I've seen quite a lot of them. Everyone is locked inside their homes, the television says that it might be a virus that leads to loss of conciense and vast amounts of rage, that is also very contaminating. Being part of the army, i was enlisted to do some patroling with one of my friends from the squad, Nigel. We didn't find any of those "infected people", but i couldn't shake the feeling that we were being watched...."
*end of recording*
"Day 8. Those things.. Whatever they are, they are not human.. not anymore.. we were chased, and we ran to some abandoned house. Their numbers are overwhelming! My AK ammo is nearly over, and there's no way i'm using that pistol unless there's a grand emergency. Even now, i can hear those things moaning.. it appears that they are hungry, and as paranoid as it sounds, i believe that they crave for human flesh.. God help us should we fall to the hands of one of them.."

*slight clicking noises, sound of gunfire, running, and a distand moan, composed of what sounds like several people. silence.*
"Oh my god they got Nigel.. They planted a bite on his arm, I barely saved him, I used the clip's last bullet to shoot that thing in the head to let Nigel go... It seems that those monsters can only be killed by a headshot, I've filled several of them with holes, and they didn't even slow down... Oh my god, what are we going to do.. the food supplies are looking pretty grim, and so is our ammunition, and Nigel is sitting in a corner of this ruined room and babbling something incoherent.."
*silence, next recording*
"Day 13. They moan. They eat, they moan, and they search for more prey.. They never stop. Never. The tv's off, it doesn't transmit anything. They must have eaten everyone in the channel's stations.. Those.. Soulless monsters... "
*concieled wimpering, then in the distance:*
"Hey man, got any more smokes? Nigel? Nigel are you listening to me? Oh.. no no. No! Nigel! No! Not you too, man! Oh my god no!"
*distant moaning*
" Stay back Nigel.. Stay back man, I don't wanna do this.. Nigel!"
*gunfire, some shouting, moaning stops, sound of something heavy falling down*
" Oh my god.. Nigel.. No... Those bastards..."
*sound corroded, tape approaches its end, and the most recent recording*
"*......*Never catch me alive! *..........*"
*gunfire, screaming.*
"*....* Go back to the hell that spawned you!"
*more gunfire*
*screaming, less gunfire, moan getting louder and closer until sounds of ripping and tearing of what sounds like skin is heard. More screaming, without big duration. More liquid-like sounds, more ripping sounds of some material.*
*end of recording*



With a shiver, and a tear running down Andrew's cheek, he placed the tape recorder in his backpack, making a mental note to keep a vocal diary himself. These will indeed be mankind's last days.
