At the time of this writing, the S.O.B. Purifier is kind of overpowering and can end a playthrough quickly. This doesn’t really let the player learn how to navigate the cooler and ruins the experience of this great game. I wanted to put out something that’ll help newcomers get accustomed to the game, so this guide is primarily for new players exploring Cooler CA-1, but the concepts learned here can be used wherever by whomever. In this guide, we are going to be cheesing the S.O.B. Purifier, so keep in mind this isn’t a guide telling you how to take him head on. That being said, the techniques used in this guide could be patched at any moment so be wary.

Melee weapon
Being that the S.O.B. Purifier has high health, having a weapon that does not use up all your ammo is critical. You could use your fists or anything really, but I recommend weapons with little to no knockback. The Cutana or the Kitchen knife therefore are my weapons of choice for this.

Swole (optional)
This helps move the process a whole lot faster, especially if the kitchen knife is being used.

And that’s it! The rest comes down to technique and luring the S.O.B. Purifier to where you need him.

So what we are essentially going to do is place ourselves in a position where the S.O.B. Purifier is right next to us, but is unable to fire directly at us. This entails luring him to a spot where we can hide from his initial fire (as he walks toward the player) and then preventing him from initiating fire again. You might be thinking how exactly are we going to do this? Simple! By either: (1) Standing behind a wall or (2) Standing above the S.O.B. Purifier. The S.O.B. Purifier tracks the player, moving as close as it possible to him/her. Exploiting this by placing an obstacle (either wall or vertical distance) in the way basically stops the S.O.B. Purifier in his tracks since he cannot get any closer. If the player does not move and does not knockback the S.O.B. Purifier, then they should be able to get as many shots as they want at this point. Let’s look at the different scenarios where this is feasible and maybe this will clear up any confusion…

Being that Cooler CA-1 is separated into 3 area types, I’ve separated the rest of this guide into 3 parts. There are many possible spots where this technique can be done, this guide just points out some of them. I don’t think I should have to say it, but finding these spots and clearing them out should be a top priority when starting a level. Make sure you can make a break for them when the S.O.B. Purifier shows up.

One place that is great to stock up on health is the medic room, so make sure to grab plenty of medistim for later levels while you have the chance. This is the room with the 4 beds, 4 computers, 2 lockers, and 2 doors.


Not only is this a great place to heal, but this is also where we will be luring the S.O.B. Purifier to take him out. Lure him in by standing in the middle of the room first, then as he gets closer down the hallway (when you can see him through the window), hop onto a bed and crouch.

Refer below to the 4K Ultra HD-detailed paint diagram for an idea of how to position yourself on the bed. As far as I can tell, this room is symmetrical so whichever doorway/bed you pick is irrelevant. I’ll be using the bed highlighted in blue in the diagram for demonstration. Crouch on the bed as he moves into the room and stay towards the corner of the bed. The wall separating the bed and the doorway will be separating you from the S.O.B. Purifier.


Notice, there are three different “zones” which I have labeled in the diagram above using the colors green, orange, and red. They are not exact, but standing in these different areas determine what path the S.O.B. Purifier will take to “reach” you. What you want to do is stand in the sweet spot (green), where the S.O.B. Purifier will try to head straight for you. You may need to move around a bit to shift his head so it is close enough to smack around. He will be blocked by the wall and stand motionless, so this will be when you get your damage in. Using any other melee weapon other than the kitchen knife will cause knockback and this will cause him to recalculate his movement to you and move around the wall…


If he starts moving towards you or you move too far to the edge of the bed (Red), then you need to shift over to the top corner (orange) so he starts to move out of the room. Crouch in the corner and wiggle around in there until he turns around. You may have some luck moving into the window when doing this to fool him into thinking you are in the hallway. Pray to the booze gods that he starts walking out of the room, or else he’ll basically have you cornered with nowhere to run. If this happens, jump over the wall and run out of the room and do the joj all over again.

Honestly it should not be too complicated to pull off. Maybe a bit tricky to get it right, but it’s simple enough. Basically you are going to be balancing him between coming to you and coming too close to you by moving from green zone to orange zone. Whatever you do, stay out of the red zone, else he will gain a line of sight on you and fire. If this happens, it is still possible to crouch your way over to the orange zone and get the S.O.B. Purifier to walk out of the room but this is very difficult with all the stun locking and disorienting from his minigun.


Extra: Sometimes this room is not immediately available, so I have used the break room to sneak around the S.O.B. Purifier, landing sneak attacks until he is taken out. I’ve called the break room the one with a table in the middle, 1 table next to 2 lockers, 2 doors, 1 large air pipe, and an L-shaped hallway outside of it.


I’ve used this area using the same concept as outlined above with the medic room, except there is no wall and you need to hide around the vent to trick the S.O.B. Purifier. Much more risky since there is no cover, but it works by the same method of making the S.O.B. Purifier walk around to where you are not. I’m too lazy to write more about it, but if you play around with the spot (vent pipe area) you should be able to work it out. If enough people want to know how, maybe I’ll write more on it…

Many of you have probably thought about this area’s cheese spot. The dormitories are full of bedrooms with bunk beds, and if you can hop on top of one then you’re in a position where the S.O.B. Purifier can’t reach you.


This isn’t the only room where you can get onto a bunk bed, but it is one of the most common and it allows you to get around the S.O.B. Purifier in case he gets too close and needs a bit of flanking to get into position.

Once again, wear your 3D glasses for this next diagram because it really is next-gen graphics here. You can get on top of the bunkbeds by the two routes in this room (shown by the white path arrows). I prefer to use the corner bed, since the S.O.B. Purifier can’t get around the other side of the bed.


As he is lured into the room, it is best to crouch down in the orange area. This moves you away from him, and crouching gives you additional cover behind the bunkbed walls. Once he is close and no longer has a line of sight, move up towards the green area and get him in a position where you can hit him. You may be able to get a sneak attack on him on your first hit. Remaining in a crouched position is helpful if you don’t have a melee weapon with a long range. Also, moving the S.O.B. Purifier to the blue spot where there is an opening in the bunk bed helps you get closer as well.

You may fall off if you get too close and that means death if you do. He’ll have you pinned down with nowhere to go, so don’t get to greedy in landing hits on him. If the S.O.B. Purifier moves too far back for you to hit him, scoot back towards the orange zone and he should move back up. If he is knocked back far enough, he’ll regain a line of sight and start firing at you. If this happens, move back to the orange zone to lure him in and once he is back in position move up.


There are plenty of beds throughout this area so finding a suitable spot should be easy enough. Just follow the steps outlined here with whatever bed you are close enough when the S.O.B. Purifier shows up and this should be a doozie.

The first two cheese spots are easy to get to, but try figuring out where the next one is:


Can you see it? Using the concepts from previous areas, you should be able to use the coolant tanks littered around this area as a spot to cheese the S.O.B. Purifier…

All we really need is a gas tank, but the best and safest spot to learn how to is in the medium sized room with 2 of these tanks. There are 2 doors to the room, 2 vent pipes along the back, and randomly scattered tables/shelves in the room. One of these shelves flanks the 2 coolant tanks, making a nice little hiding area in the back.


This room is a great way to learn to mess with the S.O.B. Purifier using the coolant tanks. Because we’re trying to learn how to use these tanks in general, I’ll be focusing on one tank in the back. Any tank can be used and I’ve used other tanks in the level when I couldn’t find this specific room in the level layout.

Take a look at the crappy drawing I made of the gas tanks in the room. Using the basic shapes of the diagram, we can see how this technique plays out. Get to the back area of the tank and wait until the S.O.B. Purifier gets close enough to break the line of sight. Once he is right next to the tanks, you can then climb on top of the tanks to start hitting the S.O.B. Purifier. There is plenty of area to move around when on top of the tank, and crouching on the side opposite of the S.O.B. Purifier (below the white line) should provide cover.


Being in the back area ensures a safe spot to retreat to while the S.O.B. Purifier is stuck on the other side. The green area is a safe spot to crouch behind when the S.O.B. Purifier is approaching, since the opening of the tank protrudes up and gives additional shielding. Keep this in mind when you are trying to lure the S.O.B. Purifier in, especially in tanks out in the open. The gas tank is fairly easy to stand up on and this spot makes it easy to watch the S.O.B. Purifier as he approaches (just remember to crouch and lie low). Once the S.O.B. Purifier is standing in the area around the blue star, start to move up until you can start swinging at him. Keep at it until the problem is eliminated.

Using these coolant tanks is nifty, but it also leaves you much more open than any of the other two spots shown above. This may not be apparent in the safe tank spot highlighted above, but if you try doing this with another coolant tank, say on one of the tanks in the 2-story large rooms, then you will be in a much more open position. The risks outlined below are for any tanks you decide to use, not only in this spot.

The nature of the tank shape makes you much more exposed and much easier for the S.O.B. Purifier to spot you after being knocked back. Your reaction to hearing his minigun turn on may be to run backwards, and depending on your and his location on the tank, he may be able to get a line of sight quickly if you fall off and he starts walking in your direction. Being that the tank is round also poses the difficultly of determining where exactly the ledge is and where exactly you should stand when above the S.O.B. Purifier. If you go too far forward, it is possible that you fall down right next to him and that spells doom. If you move too much to the left or right, he could also spot you or start moving towards you. Keep in mind that it is possible for the S.O.B. Purifier to walk to your side if you both are close enough to each other (Ex: red star and red spot on the diagram above and in picture below. These positions are obviously not possible with this tank, but are possible at other tanks). I have not tested all of the tanks in the game, so be wary about where you go jumping on top of. Things can get pretty ugly if you mess this up.

So that’s about it! You should be able to take down the S.O.B. Purifier with no problem once you got him in place. Enjoy exploring the level as you see fit and reap the rewards of his loot. Because this makes him very easy to take down, it makes getting Rifle Ammo easy. I personally prefer running through the level as normal, then as I start to get low on ammo I will go back and use the S.O.B. Purifier as a way to restock before moving onto the next floor. Sometimes when I got some good flask bonuses I’ll take him head on and just refresh my ammo after the fight by looting him.

Learning to use the S.O.B. Purifier’s AI against him is probably the smartest thing to do in this game (as is with most games) and it makes it much easier to explore the cooler. Even though I have only gone through examples in the first cooler, you can use these techniques throughout the game if you can find suitable spots. I’ll leave this up to y’all, since once you have gotten past the first cooler you should have a good basis on how the level generation and game mechanics work. Good luck.
