Strangelets could come from this. hopefully not but if so it's the end for us humans.
what are strangelets?
Seen Alien? Remember those face huggers? A lot like them.
Well, strangelets have this mammal-ish quality in them, but yeah if you think of a facehugger you get the picture.
They function in pretty much similiar way too. Jump at your face, implant shit on you, and make you a zombie-like drone. Its hard to hit these fucks with a pistol or other firearm. Crowbar is prolly your best option actually.
As a bonus, that way you save your bullets for the REAL bad guys...
Just so you know man. Be ready.
