- "Gentlemen, oil is the blood of our world. Without it, we die. Time to make sure it keeps flowing.''"
- —The Elephant when offering the heist.
Big Oil is a two-day heist in PAYDAY 2.
Contracted by The Elephant, it is exclusively a Pro Job, which means failure on either day would immediately terminate the contract. The crew must seize a fusion reactor prototype in order for The Elephant to receive support from oil conglomerates for an upcoming election.
- Locate the safe.
- Break into the safe and find the documents.
- Locate additional intel.
- Locate additional loot.
The group start outside of the headquarters of the Overkill MC, who are a group of bikers that have access to information on the location of the scientist's villa.
The group must enter the premises and eliminate the bikers. The group can attempt to silently approach the buildings or assault them.
There are always 12 bikers during the first day of this heist. Of those, there are always 3 moving guards, with the other 9 staying in the same spot throughout the entire day (not tested on death wish). The bikers are holding onto 3 separate optional assets to assist on Day 2. These assets are located on three tables in the house: the side room connected to the garage via the stairs on the first floor, the second floor landing is right next to a table, and the final piece is located on the balcony. As soon as the bikers are alerted, bikers located near the tables will move toward the table and begin to light the asset on fire. Once the biker starts the animation, you have about 1 second to shoot the biker and prevent the immolation of the asset. On a stealth assault, one could take out all the bikers and collect the intel without losing any. Going loud, a team can assign target zones to each member to take out and control to find the intel.
The often missed point on Day 1 is the massive amount of loot often hidden in the house. This is often where the majority of the mission payout is located. First, to the right of the garage, by the stairs going up into the front room, there is a locked door that can be picked or shot open. Inside of this room, there are a large number of ATM's. One team member should bring the OVE9000 saw in case a high payout is desired. One can also bring an ECM jammer as they can also open ATMs, albeit less efficiently.
Additionally, the front room of the house often contains weapon caches and cocaine, while the top floor can contain more weapon caches and money. The storage sheds around the border of the property can also contain weapon caches. These can be collected and returned to your escape van or boat for additional money. If the police have been alerted, then it is best to move the bags to the van as soon as possible before they arrive. Otherwise, the loot must be moved to the escape point while the group is under fire. Additional weapon cases can also appear in the room with ATMs and on the balcony.
- As of Update #42, Day 1 will take place either in the day or at night.
- Mines may be present in certain areas surrounding the house, moving near to one will cause a brief "detection" effect (similar to when NPCs and cameras see the player in stealth) before exploding.
- The fences surrounding the house can be electrified, causing you to be tased on contact. To check if it's the case without alerting the bikers, take out a silenced weapon, face away from the house and move backwards into the fence.
- The doors around the house may be booby trapped with flash bangs - it is impossible to tell until the door is opened.
- There may be random weapon cases around the house (the same ones seen in Firestarter Day 1).
- There may be a drug deal happening with the Cobra Street Gang in the front of the house. If this happens then there will be 4 bags of cocaine downstairs and 1 bag of money up stairs.
- There may be a Doctor Bag on the balcony, next to the radio.
- There are seven distinct pieces of intel (three of them are randomly selected to exist on Day 1):
- Blueprints – A map of Day 2, showing four points of entry.
- Intel (guard) – A picture of two circled guards.
- Intel (codes) – Shutter codes for the house. Note that you can toggle them on or off.
- Intel (scientist) – A picture of the scientist in the lab, Mr. Rossy.
- Intel (engine prototype) – A classified piece of paper indicating which the gas and electrodes the reactor uses.
- Plane keys – Allows the crew to escape via the small plane as soon as the correct reactor is delivered and verified; faster than waiting for the helicopter to return.
- GenSec keycard – Unlocks any of the three possible server rooms; one-time use.
- Note: Police are only alerted to the sound of unsurpressed weaponry, e.g. enemy gunfire, loud saws, mines. Heister explosive weaponry is fine though, as long as the gun itself is silent..
- Shooting a camera causes the biker watching the security cameras to be alerted immediately, as long as bikers in the camera room on the second floor are alive. There is usually another way around if one path to the house has too many cameras. If the camera guy is alerted he will set off the mines surrounding the house, causing the neighbors to call the cops (bypassing any ECM Jammers placed).
- An easy way to stealth this day is to use the Deagle with at least these 3 modifications:
- Standard Issue Suppressor or Monolith
- Extended Mag
- Start from the garage and work your way up through the building clearing each floor fast and carefully. Try not to break any windows as it will alert the other bikers and they will attempt to burn the assets.
- If you are playing on Death Wish, then it is recommended to have Gunslinger aced while using the Deagle. If you cannot get the skill, then use a silenced automatic weapon, like the STRYK 18c, Swedish K, Kobus 90, SpecOps or any other SMG available at hand
- The bikers will attempt to call the police if they should get alerted by suspicious activities (such as Drills, corpses, broken windows, kills without Shinobi Aced /Hidden Blade Aced etc.).
- Locate the security room.
- Hack the computer. (199 seconds)
- Open the door to the laboratory.
- Pack up the correct fusion reactor.
- Signal the helicopter.
- Take the reactor to the helicopter.
- (If wrong reactor) Wait for helicopter to return and send another reactor.
- (If correct reactor) Escape.
This day is notorious for being very difficult and time-consuming if the crew cannot identify the correct fusion reactor or at least narrow down the number of candidates.
The crew starts outside on a hilltop, and they must gain access to the laboratory within the mansion. To do so, they must access one of three locked security rooms, and hack the system within.
A stealthy approach is recommended. There can be 5 - 7 guards on day 2. To figure out if there are 6 guards instead of 5, there will be 1 guard standing idle at the front door of the building. There are several cameras scattered around the mansion, each one is viewable on the camera feed asset. The crew may wish to kill 3 or 4 guards to clear the map of guards, leaving only a few left patrolling.
There is exactly one civilian, Mr. Rossy, who is either in the lab, outside the back of the mansion next to the pool or on the far side to the left of the pool, in his office on the second floor next to the server room, or sitting out the front of the mansion on the park bench next to the basketball.
Each security room door can be opened with a drill, OVE9000 saw, three shaped charges, ECM jammer, or a keycard if it was found on Day 1. The system takes 199 seconds to hack. It can take longer if the police are alerted since they will constantly attempt to turn off the power with either of the two randomly placed circuit boxes.
After the hacking is completed, the crew can open the door to the lab, which is in the middle of the first floor. It contains 12 fusion reactor prototypes. At this point, DO NOT indiscriminately bag up all reactors as it will make the mission much harder as identification of the correct reactor is now impossible. The crew must find out the correct reactor to deliver (see the section "Finding the correct fusion reactor"). Once a reactor is bagged, a player can signal the extraction helicopter with a flare outside. If the crew did not narrow the number of candidates to one, then they may wish to carry multiple reactors to the extraction zone at once.
The reactor is extremely heavy and slows the carrier down to a crawl, so if the police are at the scene, they will need to be escorted. In this case, it is advised that an Enforcer with defensive skills carries the reactor. If the carrier needs to run, whether it is to recover their armor or to save a downed crew member, they can drop the bag, and resume carrying it later or have a crew member take over.
When the helicopter arrives, the alarm will automatically sound if it has not already. Place the reactor in the helicopter, and Bain will take a few minutes to verify the reactor. During this time, the crew should find a defensible position, such as behind the hill next to the extraction zone, or back in the lab.
If the wrong reactor was delivered, then the crew must repeat the process and extract another reactor. After the correct reactor has been delivered and verified, the crew must either wait for the helicopter to return for extraction, or if the airplane keys were found on Day 1, escape with the airplane near the crew's spawn.
- If you obtained the shutter codes intel from Day 1, you can toggle all of the upstairs shutters which covers most of the windows.
- If the shutters are open (random chance), or you obtained the shutter code intel, it's possible to see into the two upstairs secure rooms to identify the server room (the third is on the main floor and has no windows). You can still see through the sides and bottom of the shutters to identify where the server is even if they are closed.
- Guards will be alerted if they see the computer being hacked.
- If you bought the Alex Ammo Drop, there is a chance he might drop the ammo bag somewhere inaccessible, like on a tree, a hill, or at the bottom of a cliff.
- The engine delivery is one of the very few instances where bags carried away by law enforces actually benefits the player crew, as a law enforcer is not slowed down by any significant margin while hauling the engine bag and their loot rendezvous points are usually near, or can be intercepted as they near, where the loot chopper lands. As such, it is advisable that the team bag up all the possible engines and leave them within sight and reach of other enemies and intercept them as they near the extraction zone.
- Avoid using explosives inside the house as the explosion may destroy the computers, preventing the ability to determinate the pressure of the correct engine.
Finding the correct fusion reactorEdit
Once you have entered the lab you will be faced with 12 fusion reactor prototypes. In order to complete the heist, you must determine the correct reactor to extract. There are three parts to solving this puzzle; the correct fusion reactor is the one with the correct gas tank color, correct number of nozzles connected to the large blue hydrogen tank, and the correct pressure reading on the gauge.
A tool to help choose an engine based on these parts can be found in the section "Engine layout".
The correct reactor uses one of three possible gases, matching to a different color gas tank as seen on the whiteboard at the bottom of the stairs in the lab. These colors are always the same.
- Deuterium (blue tank)
- Helium (green tank)
- Nitrogen (yellow tank)
On Day 2, a spiral-bound notebook with one of the gases written on it is randomly placed inside the building (in the lab, or on a table or desk upstairs). It can easily be overlooked if it lies in the lab as it is often in shadows; a tactical light may help to locate and read it.
Number of nozzlesEdit
There may be a clipboard in the house or lab with notes that indicate the number of nozzles. Near the bottom of the paper, there is a number or symbol followed by "× H"; a number represents the number of nozzles attached to the reactor. If a lemniscate (∞) is present instead of a number, it represents one nozzle.
Inside the lab are several monitors, one of them displays a psi value at the top-right part of the screen with a "≤" or "≥" symbol. The value should be either 5812 psi (401 bar) or 5783 psi (399 bar).
If the symbol on the monitor is "≤", then the correct fusion reactor's pressure gauge reads less than or equal to the value shown; if "≥", then greater than or equal to the value.
Care must be taken inside the lab so the monitor containing the pressure statistics will not be accidentally destroyed and make the identification process much harder.
Cold Fusion ResearchEdit
One of the assets you can obtain on Day 1 is the "Cold Fusion Research Paper". Highlighted in pink in the first paragraph is the name of a specific element. This could be palladium (Pd), Titanium (Ti) or Platinum (Pt).
This will match to a whiteboard in the lab. For each row, from left to right, there is a number followed by H (number of nozzles), then inside the next column there will be a chemical equation, headed by one of the gases and the catalyst:
- Platinum (Pt) is added to Helium.
- Titanium (Ti) is added to Nitrogen.
- Palladium (Pd) is added to 2H (Deuterium).
By matching your catalyst to the row, you can determine the number of nozzles and the gases, completely bypassing the usage of clipboards.
The following table shows the relative location of each engine and its properties:
- The engine number.
- The color and contents of the gas tank. (Deuterium, Helium or Nitrogen).
- The number of nozzles attached.
- The pressure reading compared to 400 bar. (> is greater than 400, < is less than 400, = is equal to 400)
D 3 >
He 3 <
D 1 >
N 1 <
He 3 =
D 3 <
N 2 =
He 2 =
N 3 <
N 3 >
He 2 >
D 2 <
There are two ambiguous cases:
- Helium, two nozzles, and ≥ 5783 psi could be engine 3 or 6.
- Helium, three nozzles, and ≤ 5812 psi could be engine 7 or 10.
If the reactor has only one nozzle, then the element is not required to determine the correct reactor.
- ≤ 5812 psi and one nozzle is engine 1.
- ≥ 5783 psi and one nozzle is engine 2.
Death Wish changesEdit
- Day 1
- There are two or three Titan safes; only one of them contains the address, and the others contain a bag of money, a gold bar, or nothing.
- Three extra bikers patrol outside, making a total of 15 bikers.
- The chance of a drug deal happening between the Overkill MC and The Cobras is increased.
- Day 2
- All cameras are Titan cameras.
- After picking up an engine, there is a chance that the flare must be lit next to the pool instead of on the airfield. This location is open to sniper fire, but much closer to the mansion. Before the helicopter lands, it is best to keep the reactor behind the big seat at the corner of the pool, as the helicopter's door will be right next to it.

- Big Oil is internally referred to as "Welcome to the Jungle".
- Some players are reporting a mysterious message which may pop up during the first day of the heist saying: "Take the key from Chavez", a reference to the "Panic Room" heist from Payday: The Heist. Also, if the "Alex Ammo Drop" asset has been bought on day 2, Bain can make a reference to "Panic Room" as well. In the reference, Bain says "Panic Room all over again."
- It is not possible for the electrical fence in Day 1 to incapacitate a player, they will free themselves after a short period of electrocution.
- On the balcony of the biker clubhouse (Day 1), there is a radio that plays any song from Payday: The Heist.
- If the crew manages to acquire the randomly-spawned Shutter Codes on Day 1 of the heist, they could use it to close the second floor shutters on Day 2 that would block off the entire back part of the building, leaving the only way in and out through the first floor doors and windows.
- Deuterium is misspelled on the whiteboard showing the colors of the corresponding gas tanks.
- The scientist Mr. Rossy (Day 2) is most likely a reference to the convicted fraudster Andrea Rossi who claimed to have successfully demonstrated cold fusion in 2011.
- One of Bain's mission success quotes talking about "You guys know who Tucker is? I hope you don't" is a reference to Preston Tucker, an automobile developer in the 1930's who was subjected to corporate sabotage and espionage by other automobile conglomerates which led to his eventual bankruptcy.
- The idea behind the Tucker reference is reflected in the nature of this heist: patent theft, Tucker of his sedan patents and Mr. Rossy (the scientist) of his prototype fusion engines.
- On December 2013, a bug caused "palladium" to always be written on the intel. It has been resolved in Patch #67, over a year later.
