ok...did a quick google on pennywise...he's just a man in costume right? I choose that....or....
how many zombies i gotta run through? I gotta kill them or just get up past their floors?
Breh, Pennywise is a gigantic inter-dimensional spider-like creature. The clown was just its way of projecting itself from underground. Only way youre surviving is to go underground and somehow kill it. And five of them at the same time? Impossible.
Realistically, the only things on that list you can beat, are the rabid Cujos or the Bolos. Its only possible if youre facing off in like 2-3 story house with lots of places to run and hide and sharp or heavy stuff to attack the dogs. If youre trapped in a car like in the book, then youre fukked.
For the Bolos, well, those dudes are human, so I mean, you got a chance if you can pick em off one at a time.
