Reactor A5

## Overview

Reactor A5 is a map that was added in the 1.27 update. It is one of the most detailed maps in the game, with several different rooms and destructible features such as a reactor, lift, control panels, spotlights and other items that are exclusive to the Reactor A5 map. The reactor can suffer a meltdown, where, when it does, a green effect will be applied over the screen. It's implied the reactor doesn't have an anti-meltdown override, but cooling and low temperatures has devastating effects on the reactor.

The lift connects the corridor with the office. The lift features 3 buttons, an up, down, and emergency stop; these buttons are in the corridor, on the lift, and in the office. Moving the lift or any part of the mechanism manually will result in the ropes breaking, therefore causing the lift to fall.

## Rooms

The Reactor A5 map has 6 different rooms. These rooms are 4 mirrored command centers, an office room, a reactor room, a room with a podium, and a corridor. Due to the presence of these rooms, it can be speculated that the Reactor A5 map may be a bunker, underground lab, or some sort of power generator for a large facility.

### Reactor

The reactor room is the biggest room in the map. There are no lights in this room. The reactor consists of 3 parts and 2 pipes. Its base temperature is 3000°C. Above 7500 degrees Celsius, the pipes will begin to explode one by one, leaving marks on the reactor. If the temperature reaches 17000°C, which is the critical temperature of the reactor, a siren will play and the whole map will begin to shake. Eventually, the reactor will explode, leaving a steam effect everywhere on the map. At around -150 degrees Celsius, all the pipes will freeze and fall off the reactor.

    You can put objects in the upper part of the reactor, known internally as the 'vacuum chamber'. Occasionally, lightning will appear between the electrode on the ceiling and the electrode mounted on the upper section of the reactor. Under the reactor there is a pool of light brown liquid that is probably waste. If you put a human in this liquid, they will get skin damage and begin suffering burns.

The vacuum chamber has no oxygen at all and has extremely strong radiation that can even destroy androids.

If you detach the pipes, the reactor will heat up. The reactor can be detached from its base and it will fall, but it has no effects on the data monitor whatsoever. Inside the reactor, there is a network of pipes used for cooling. You can see the status and abstracted map of these pipes on the data monitor.

### Command centers

There are 4 command centers with a control panel in each one. In two of the rooms (top right and bottom left) you can find a monitor with data about the reactor.

None of the command centers are connected, however there is a door in each one, meaning that they may be connected 3-dimensionally. These doors do not work as PPG is a 2D game.

The command centers on the left side of the map control the rod depth, with the top one decreasing, and bottom one increasing.

The command centers on the right side of the map control the cooling pump percentage, with the top one increasing, and the bottom one decreasing.

### Office

The office is the second largest room. It features 4 desks, three on the platform; two on the floor, each one with an office chair, computer, monitor, and keyboard. It also features a level consisting of three suspended platforms, which can be made to fall with enough force exerted onto them, similarly to the lift mechanism, though slightly stronger. This makes it the most destructible room in the game, as each of these objects have physics. This room also has a lift which connects to the long corridor that leads to the first command center.

In the bottom right corner, there is a step down transformer along with a non-functional control panel. You can connect an electrical wire to it, which will produce far more electricity than the industrial generator, making it the strongest power source in the game. The transformers make a strong buzzing noise. They are also connected using a unique type of cable, which isn't seen anywhere else, nor can it be chosen in the tools sidebar.

### Podium

The podium/auditorium room is a room with a staircase and what seems to be a podium on the far right side. The podium appears to have a handrail of sorts and a singular wooden chair. The staircase has 63 steps and is approximately 13m tall. This room also features a spotlight which is named a "Projector", however unlike the actual spotlight item, it is much dimmer and you cannot rotate it, therefore it always points towards the podium. This room also features some unusual floodlights on the roof, unlike any other seen in the game. These floodlights cannot be interacted with or spawned in-game.

### Corridor

The corridor is an approximately 56 meter long corridor connecting the first command center with the lift which leads down to the office. The corridor has one fluorescent lamp, which creates light which is more blue than anywhere else on the map.

## Data Monitor

### Diagram

The data monitor features a diagram of the reactor, which includes an abstracted map of all the pipes inside. If a pipe network gets damaged, the corresponding pipe will get marked as either flashing yellow, solid yellow, yellow and red, flashing red, or solid red, depending on the severity, as well as an alert ping will sound intermittently, depending on the severity of the damage. The two pipes that are connecting to the circle in the diagram are the large outside pipes.

### Temperature

The temperature of the reactor depends on the cooling pump percentage and control rod depth. The higher the control rods, the quicker the temperature **increases**. The higher the cooling pump percentage, the quicker the temperature **decreases**.

The reactor starts off at 3000°C, and starts off with the temperature slightly decreasing. Under 1000°C, the data monitor begins displaying a "LOW TEMPERATURE" warning. At around -150°C, all the pipes freeze and fall off the reactor.

Above 5000°C, the data monitor begins displaying a "HIGH TEMPERATURE" warning. Above this point, the higher the temperature, the more likely for a pipe to bust. At 10,000°C, the monitor displays "CATASTROPHIC TEMPERATURE", an emergency alarm sounds across the entire map, the entire map shakes, and eventually, the reactor reaches a state of prompt criticality triggering a nuclear meltdown.

Temperature is directly proportional to the physical temperature of the pipes.

### Cooling Pumps

The cooling pump percentage is the percentage of coolant that flowing into the reactor. This can be adjusted in the control centers.

The **higher** the percentage, the **stronger** the cooling.

The **Lower** the percentage, the **weaker** the cooling.

### Control Rod Depth

The control rod depth percentage is how high the control rods are. The higher the percentage, the lower the temperature. This can be adjusted in the control centers.

The **higher** the percentage, the **stronger** the cooling.

The **Lower** the percentage, the **weaker** the cooling.

### Reactor State

The reactor state cycles between critical, subcritical, and supercritical.

Critical is the normal state of the reactor, including when the map is first loaded, and refers to a small or non-existent change of E within the reactor. Even if E is especially high or low, it will remain critical if there is only a small change. A significant stage seems to be about 3000~ per second.

Subcritical means that the level of E is dropping at or above 3000~ E/s.

Supercritical means that the level of E is rising at or above 3000~ E/s.

### Power Output

The power output is measured in 'E' units. It is unknown what it stands for. It appears that the higher the temperature, the higher the power output.

## Misc.

### Secrets

* A door in this map has a 0.2% chance every second to play a knocking/banging sound.
* Connecting a flask to one of the pipes inside the reactor with the liquid conduit gives you coolant.
* There is a chance of an anchor spawning in the coolant underneath the right command stations on map start.

Trivia

* The pulleys that hold the lift are named "The heaviest object known to man"
* If you tear off the pipe from the reactor and push it with it, the reactor will break and fall apart.
* The brown liquid (Reactor waste) is room temperature, but dropping a gorse or a human into it will cause them to burn and heat up because it is acid.
* Brown liquid has melting point of 10 Celsius and it evaporates at 440+ Celsius
* In earlier versions of this map, the whole map was floating in an abyss.
* Like all other maps in the game (bar Uncharted Territory), this map has a description, reading "A replica of one of the many reactors of the facility, complete with surrounding rooms."
* In earlier versions of this map, deleting a data monitor would delete the entire map.
* After the meltdown, a strange effect is applied to the screen, and changes the color palette, suggesting high levels of radiation.
* In the office, on the suspended platforms, the middle desk's computer will play faint looping music when activated, stopping once destroyed or deactivated.
* Objects can be spawned inside of the reactor and seen through the black circle. They will pulsate and show burns without fire as if they are being bombarded with radiation. This occurs to Androids too and is often deadly.
