The pulse is an unknown shockwave found within the mines. It occurs approximately every six seconds, and the only warning given before each wave is a distant flash of light and a build-up of bellowing wind. Objects in front of the wave will be violently blasted away and broken apart, including the protagonist. Sturdy objects and walls are the only methods of protecting against the pulse.

Location[edit | edit source]

The pulse is located within the mines, which is Sector 2 of the facility. It is found in a massive subterranean cavern, large enough to have its own shoreline and beach. The cavern's entrance and interior contain mining equipment and work stations, along with remote albinos dressed in work clothes, suggesting that the vast atrium which holds the pulse was mined out.

Atrium[edit | edit source]

The gate to the atrium is only able to be accessed if the weight of twenty individuals is placed on a pressure-sensitive plate. The protagonist completes this by controlling the various mining workers around the area to follow him.

The atrium's initial area contains sandbags and still-functioning construction equipment as the protagonist progresses, alongside mechanically manipulated blast shields, of which, several seismometers can be seen nearby.

Many fans believe the pulse was designed as a failed sonic-based/seismic weapon. This assumption is supported by the presence of multiple bound crash test dummies in chairs, and a man-portable blast shield that is able to be used for deliberate protection against the pulse. Also, the fact that the pulse can hurl objects, such as barrels or boxes, at speeds that can damage concrete indicates that the pulse is most likely a mass destructive weapon.

Another possible guess is that the pulse was used for mining rock beds like the one seen before reaching the atrium. However, the pulse does not indicate any ability to break apart rock or metal, making this guess implausible.

Another guess is that the Pulse is controlled by scientists as a way to keep intruders/albinos away from the other sectors.

A fourth theory is that the pulse is a way to disable mind control tech of it were to get out, as shown when the protagonist first enters the atrium and the mind control hat is blown off of his head in a burst of electricity.

Trivia[edit | edit source]

  • In the room above and to the right of the pressure plate, where the body of the last albino needed to reach the count of 20, there is some kind of large device with a needle dial, and a cylindrical mouth projecting through the glass wall overlooking the shockwave (pulse) atrium. The mouth of the device bulges in sync with the pulse, as does the needle on the dial, moving all the way to the right. This devices could either be a measurement device, but the bulge seems to indicate this could be the, or one of many, pulse generator devices.
  • The music that plays during the pulse is synced directly with the coming and going of the wave itself. During the second half, the music changes from heavy wind sounds to an electronic rhythm.
  • The oddly-specific weight of 20 people required for the pressure plate may indicate that the Huddle is composed of 20 bodies, granting the Huddle access to the atrium.
    • Conversely, the Huddle may be less than or more than 20, meaning the Huddle will not be able to activate the pressure plate (assuming the plate does not work with more than 20 bodies).
  • Given the time between the pulse flash to the shockwave that reaches the protagonist, the source of the blast is around 843 feet (256 meters) away from the bridge.
  • If the protagonist returns to the pressure plate after his mind helmet fizzles out from the pulse, the albinos will still assist him in lifting him up and throwing him. Each time, the albinos step forward a short distance. With enough patience, the albinos can be lead into the atrium and the protagonist can be thrown onto the large box before it is destroyed. However, this does not affect anything, and there reaches a point where the albinos no longer step forward (so it is unknown how the pulse would affect them).
