hello everyone I'm so hungry and I like
to welcome you back to the gungeon in
this video I'm gonna explain how you can
get to the resourceful rat boss fight'
there is a lot of steps to this so I'm
gonna try to be as specific as possible
so let's jump right into it
step one and step two can be either/or
so you can do these in whichever order
you want for step one and step two so
number one you need the nod key this is
found on floor number two in the shop it
does cost $1000 but this can be given
over the course of multiple runs and
after you purchase it once it will
always be available for a hundred and
fifteen dollars now in order to get this
to show up you have to have the bullet
that can kill the past I'm not gonna go
into depth on how you get that but that
is the thing that you need to build with
the prime primer the Gunpowder the lead
and the shell casing now this key can
also be stolen and if it's stolen before
it is purchased for the first time it
will return the next run with the price
before it was stolen so I recommend just
committing a couple runs to investing in
the key if you're having a hard time
getting the money I recommend going
through the sewers a couple times and
you should be able to get a thousand
dollars in no time so once you buy that
key from the shopkeeper that is step
number one now you do have to buy it
every single time you want to try to
access the rats lair and it is 115
dollars each time you go on a run so
keep that in mind you will need more
money unlocking it is not good enough
you can steal it though if you have a
item to steal with number two you need
to get the rats infuriating notes there
are six of them now these are found
randomly in any type of chests also one
will appear from a mimic
now some notes won't appear until you do
certain things so here's a list of the
things that you need to do you need to
beat the first floor
get something stolen by the rat you need
to enter into the sewers you need to
obtain a master round you
kill that new bomb boss and you need to
have killed the hydreigon which is the
final boss or the fifth floor boss and
then after that you'll be able to obtain
all the notes through chests now you
don't necessarily need these notes to
find the wrath
although it's gonna be way more
difficult and it's gonna be super
frustrating so I recommend not even
attempting the rat until you get each of
these notes and just note that getting
these notes will probably take you a
while because it just comes out of a
random chest so don't get frustrated
just do a couple runs and you'll get the
notes over time alright so this is where
it gets kind of confusing so after you
have paid the thousand dollars for the
key and you can unlock it on the second
floor for a hundred and fifteen dollars
and you have all six of the notes you
are in good shape to go to the rats lair
so start afresh run and I recommend
going through the sewer if you can if
not you should be able to accumulate
enough money if you don't buy anything
from the shop on the first floor or the
second floor you should still have
enough to buy that key for $115 but you
might not have enough items or weapons
to fight the rat so I do recommend going
through the sewer you can even go
through the next secret zone with the
the King I can't remember his name right
now but you unlock that through the
sewer with the armor piece so you could
do that if you want to have even more
money so I would pick your best
character start out save up the money as
you go through hope you get lucky
because you're gonna need a little luck
with this as well for money and also
items you're hopefully the bosses are
gonna give you some good items and stuff
like that and I do recommend either the
pilot or the bullet simply because you
will have the lockpick so you can
lockpick some chests along the way and
hope you get a good weapon or a good
item and then if you start with the
bullet you got the sword and the sword
is in my opinion the best starting
weapon because you can hit bullets away
and it also does a fair amount of damage
as long as you have full health so once
you get to the second floor buy the key
and then go to the third floor now the
third floor is the most important floor
here you
need to have two blanks or at least one
armor and one blank so make sure you
have that also make sure you have that
nod key from the second floor and then
all you need to do is keep your eyes
peeled for a room on the third floor
with a bunch of rats running around now
in this room there will be a spot that
you'll notice your character will be
kicking up more dust than usual so just
walk around on that area and it will
unveil a secret hatch and then open that
hatch with a key I should have mentioned
before that you do need one key or you
can try to lockpick it as well but
either way you have to open that hatch
so once you're ready open that hatch
fall down and then go all the way to the
right on the minecart once you're at the
end you can either blank the passage
open or if you have armor you can roll
off the minecart and it will blank for
you and then once you walk up the path
more you need to blank again here you
will find another hatch but this time
you put the nod key in and then you fall
down to the rat Slayer this is a maze
that is why I do not recommend going
down there without these infuriating
notes from the rat now this part can be
a little confusing but fortunately once
you learn the route you have to go it
does not change or at least it has not
for me and I've went down here probably
like six or seven times already so for
this next part I recommend looking at
the ammo nomicon before you fall down
this next hole because once you fall
down the hole you will be on a timer and
it won't show you the timer but if you
take too long or take the wrong path
it will just kick you out of the maze so
make sure you know where you're going
ahead of time so open up your ammo
nomicon and then you go down to the
infuriating notes on the bottom and you
will notice that there is little hunks
of cheese on the notes and they will
point in different directions and the
first note will have one direction the
second note will have the next direction
the third note will have the third
direction and so forth so I recommend
writing down on a piece of paper which
directions you have to go so in my case
I have to go down right down left left
and down so once you fall in this other
hole here you start there
pattern and this part can be kind of
tough it's got harder enemies but use
your best weapons don't save anything
because once you get to the end of this
maze you get ammo and you get health so
I would just use your best weapons right
away also you can do this without the
notes but the chances of you guessing
the right direction is very slim so I
just recommend getting the notes first
so after you run through the maze and
collect all your ammo and stuff all you
have to do is walk up and you will be
greeted with the resourceful rat boss
fight and I'm gonna briefly talk about
this fight as well since we're here this
fight can be really challenging so I do
recommend having a lot of guns and a
good active item the first part takes a
little bit to learn he's got some really
crazy attacks you can do and he shoots
them very fast so you got to be on your
toes in my opinion his hardest attack is
when he shows the laser grid and then
you have to go in between the lasers to
avoid getting hit so just focus on your
character and try to blast them and then
that the next phase will be in a giant
mech suit and hopefully you'll have some
blanks left for this part because this
part can get pretty challenging but if
you have good guns and you're able to
avoid some of the chaos for a little
while you might be able to best them
here now the third part is really really
hard
it is based off the punch-out game and
the better you do here the more keys you
will get from him to unlock the rewards
after this fight this fight is
incredibly difficult in my opinion
there's three different phases so you
really have to practice up there's a
bunch of different attacks you can throw
out you I know when he does the spin
attack you cannot duck that you must
block that so that is my one tip for you
also if you want to get all the keys you
have to end each round with a three-star
super punch so that's pretty hard in
itself in order to get the super punches
you have to punch the rat right when he
flashes yellow that will give you one
super punch and you can see how many
super punches you have by looking up top
on your health bar it'll be a white icon
that looks sort of like two swords
crossing with a third one behind it so
you need three of those and you need to
knock them out in round one too
and three with a three-star super punch
in order to get all the keys and in my
opinion this part is probably the
hardest part in the entire game because
this rat is really good at punch-out but
if you do manage to beat them in all
three rounds the rat will give a speech
at the end and you can kick around his
dead body which is pretty interesting
and then you can also open up all the
chests down below which would include a
bunch of different weapons from the rat
and if you collect them all you turn
into the rat which is pretty cool and if
you blank in that room it will show a
secret passage where you can unlock and
get a serpent I'm not exactly sure what
the serpent does I think you have to
feed it different items for it to follow
you so that's pretty much it I hope you
guys all enjoyed this video if it helped
you out make sure and leave a thumbs up
I would appreciate that and let me know
in the comments if you beat the rat I'm
really curious to see who beat him out
there and I think this fight is very
hard it's comparable to the Lich maybe
even harder than the Lich but at least
you don't die if you don't beat him in
the punch-out you still get the rewards
and you can still continue on with your
run if you want to which is cool and
that's pretty much it so I'll let you
guys go I hope you all enjoyed the video
good luck and have a great day
