Methos guides hey guys Mackey here
continuing the doom 100% walkthrough
showing you how to get through the level
as well as all 100% missable
collectibles and I even show you the
challenges and the best way to do those
in this one there are like 15
collectibles three challenges I'll be
showing you how to get through the level
pretty fast the level is somewhat
open-ended but you have to kind of do
certain things in certain order to get
through from the very beginning jump
across to the left go into the room get
the drone and pick up the data pad and
then here if you get lucky on this shot
you might be able to kill three enemies
with one barrel explosion as part of the
challenge definitely not the best place
to do it but it is possible so just give
it a try if you can't too bad we'll do
it later then from then on there this
enemy right here is called a soldier
we're gonna need to kill three of them
with a curb stomp glory kill to do that
make sure they start glowing red and
then do a glory kill from above them in
order to do a curb stomp after that we
can proceed forward and pick up the chip
off this dude by falling down in this
hole between the large gap in the
catwalk above us now we'll have to run
back up to the top as part of you know
to get something for the story before we
reach where we're going there is a
little secret so upon crossing this gap
going back to the level we were just at
go into this vent in order to find a
secret the secret is just the area not
the actual vest itself jump back down
now we can get across the catwalk this
is the opposite side of where we entered
to pick up this guy's arm we're gonna
need this guy's arm to go back to the
computer before and we're gonna need to
scan the computer to open a door which
will take us to our first nest there's a
total of four nests we do kind of have
to do them in a certain order but it's
not extremely specific as to what order
you do certain things in so this is the
fastest order to get through this level
put the arm on there the door opens go
inside pull out the nest and then kill
all the enemies
you've noticed probably if you've been
watching along I like to glory kill my
enemies shotgun them and train saw them
this is the fastest way to get through a
large group of enemies but if you're
playing on a harder difficulty it
actually might be advised that you use
your shocking a little bit more more or
less often than I do and whatever once
we clear this room I'll rejoin you back
with the commentary there and by the way
there are no soldiers in this room so
don't worry about getting the glory
kills from above
demonic threat reduced by 25% so after
that we're gonna go back to basically
what is the beginning of the level where

Watch video from 03:00 - 6:00

we started and now to progress the level
we're gonna need the yellow key card and
then we're gonna do a whole bunch of
things to get the blue key card and on
the way we're gonna grab a whole bunch
of secrets and stuff so if you go across
and then stick to the back left here
you'll find this dude on the ground
that's a soldier by the way I tried
glory killing him I was unsuccessful
pick up the yellow key card off this
dude if you find any other soldiers that
you're able to get a good glory kill on
I would recommend doing that although it
can be a little difficult
that guy just I was a regular glory kill
so to do a above death from above glory
kill you have to have significant height
on the soldier when you melee him and
he's you know glowing orange so just
make sure you jump and you're like
directly above his head as you try to
glory kill him
from that yellow keycard guy though
after we kill everyone basically like
directly under that area there's this
secret area where we can find the secret
area and pick up the doll collectible
and then from there we're gonna run to
the very middle section of the foundry
to find a secret glory killing anyone on
the way
so as you just saw there I'm now two for
three that's the easiest way to get a
glory kill literally just keep mailing
them and then jump over them and mail at
them in the top of the head now that
we're in the very middle of the area
pulled the lever which will open the
secret door which is right across the
bridge from where we started and just go
inside once it says secret found dip
back outside
now this right here is without a doubt
the best and most repeatable area to get
the challenge for killing three enemies
with one barrel explosion I'm running
around in circles to get the enemies to
kind of converge into all one area and
then I'm gonna shoot the barrel when
they're all right next to it to make
sure to get three or four even five
kills up to five six kills if you're
really good to get that challenge out of
the way I continue killing the enemies
and I'm doing a little bit of a cut here
just to include the challenge in there
and and whatnot you want a glory kill
this soldier dude if you can get a
chance to finish off that as well so now
we've gotten all of our curb stomps as
well as our three and one barrel
explosion and all we have to do is find
a couple more secrets in order to get
the other challenge so the challenges
are basically out of the way completely
and there's quite a few more soldiers
left by the way in the mission so don't
worry if you haven't gotten it yet just
keep your eye out for the soldier
enemies in this corner not far from that
room we can find the Argent cell where

Watch video from 06:00 - 9:00

are these called these are the upgrade
points I forget the exact name right to
the second but you can equip it to your
health armor or ammo I'm gonna be
picking ammo for the majority of my
early ones here and then from that
location where we are going to now go to
where we can actually use the yellow
keycard all this stuff that we just did
was a little bit extra in order to make
sure to get all the secrets and
collectibles so we're gonna go through
this door and at the top of the top of
the door on the computer console we can
find a data log now there's gonna be a
whole bunch of really big dude spawning
sometimes they'll follow you sometimes I
don't know where they come from take
care of them the best of your ability
they're quite strong if you have a full
chainsaw you can take it down with like
three of fuel units otherwise I would
just recommend using like explosive
bullets in your shotgun or the mini
rocket upgrade on your assault rifle
continuing on from there we're gonna
enter a room with a bunch of crates on a
conveyor belt and some arms working on
them jump into the middle crate to pick
up the second of two dolls and find a
secret as well from then on there follow
the conveyor belt to the very end you'll
see some boxes stacked up next to a lock
door jump up on those boxes to
find a small little vent at the very end
of this vent you can find a soldier and
then you'll want to go back downstairs
into the conveyor belt room and kill all
the enemies of the door opens
once the door opens go inside pull out
the root of the nest and kill all the
enemies that spawn
after killing all the enemies you should
be able to jump across from the middle
of the stairs across to a ledge to find
the auto map this isn't mandatory for
anything but it does help you with some
stuff on your map if you're curious and
then from then on there we can continue
through the door to exit that area and
pick up the blue keycard

Watch video from 09:00 - 12:00

this is a keycard that is required to
progress through the story so now we're
gonna jump back down we're jumping back
down into an area that might seem
familiar and you'll see that there's a
door leading to the blue area now we're
not gonna go through that door just yet
because we don't want to trigger too
much of the story to happen and then
have trouble getting back you know into
certain areas so instead we're gonna go
to the lowest floor and through this
yellow door then jump down and then look
left and you'll find this data pad on
these garbage or barrels or whatever now
that's a little bit difficult so just
make sure you slow down the video if you
have to but from there we're gonna jump
through a window in that same room clear
out the enemies go forward through the
hall sticking to right-hand turns
whenever there is a fork in the road
so fork in the road turn right fork in
the road turn right and then it will
drop down here and you'll notice that
there is a ledge we can grab on to or
want to grab onto that ledge on the
right-hand side of the room go into the
room and find the secret just by being
in the room pick up the rocket which
will actually be a weapon that you can
use throughout the rest of the game
highly recommended that you do this now
from here on out we're gonna go back
into the main area of the foundry you
can kind of exit whatever way you like
my way might be a little bit complicated
for you if you're not familiar with the
level it's honestly even a little bit
complicated for me having done this
level three or four times now eventually
you'll end up outside and you'll notice
that there's a Gore Nest and this one is
kind of like it's kind of below where we
were with the doom level the original
doom level Easter Egg secret with the
believer it's kind of in that general
direction but essentially take it out
and kill all the enemies that spawn
after that and now after all of that
another curb-stomp if you need them
here's a good area to farm a couple of
them for that challenge after that go
back to the
blue doors so this one's at the lowest
possible level where I am right now this
is the lowest possible level in the
boundary that you can stand on that's
not hot lava anyways after you cleared
all the enemies which you can actually
skip I think to be completely honest
you'll kind of go back to where we
started the level and you can find a
lift and that lift will take you back up
to the highest level which we'll need to
do in order to find the blue doors which
is where you'll see me go after killing
the floor enemy

Watch video from 12:00 - 15:00

so now that we've gained entrance in
through the blue door there's like three
or four different doors so just go which
through whichever one you find first
destroy the nest it'll spawn a whole
bunch of enemies kill all of those
enemies in order to survive the round
and open the doors because currently the
area we are inside is on lockdown
after you kill all of the enemies I
would advise you to walk out of the blue
door that faces the beginning of the
mission to the right of that door you'll
find a new air lock type door
it's a giant yellow door that will open
after you kill all the nests and do all
the objectives and then forward in
through this room you'll find a control
panel and this will start a large battle
which will last you anywhere from like
three to six minutes depending on your
difficulty and out well you're doing so
just kill all of the enemies until it
says everyone's neutralized the music
will kind of calm down the lights will
turn on and one of the doors at the top
of these stairs will also open

Watch video from 15:00 - 18:00

the core temperature is now stabilized
all right so eventually all I kill all
the enemies came to the door it opened
with a green sign on it and you'll find
an elite guard right in front of you as
you enter obviously I want to take his
chip from here on out you should have
everything if you press the back button
inspect your map or your you know your
general mission overview you should see
that you have 100% of all the
collectables and the challenges should
be done and whatnot interact with the
shutters to open up the shutters to find
this person in here and wait till that
cinematic ends and then soon after that
we can end the mission
she is trying to tear open the portal
between our world
there's
you could not have
to end the mission just keep waiting
until that girl leaves kill the enemies

Watch video from 18:00 - 21:00

that spawn and then the door will open
go inside of that door and then exit the
facility to finish it off thank you guys
