RPC Authority

RPC-XXX is contained within a specially designed 20ftx20ftx20ft containment cube at Site-██.

Instead of 20ftx… use ^superscript with ^ to make it 20ft³.

Any issues or damages in the containment structure are to be immediately reported to Site Security for repairs.

End the sentence at "immediately reported" or you can change "to Site Security" to "to Containment personnel. Just a nitpick really.

The containment chamber is equipped with a maze-like layout consisting of designed with 3 false exits and 5 interconnected corridors |. This design serves in order to confuse and impede RPC-XXX's movement in the event of a breach, providing additional time for containment personnel to respond. All corridors within the chamber are to be equipped with surveillance cameras. The entrance of the cell should be welded shut at all times, but can be removed should the need for recontainment arise.

I cut out "providing additional time" because the why of the containment protocols are for the description.

In the event significant damage is done to the primary containment cube, a functional replica of the cube is to be on standby. Ensuring a seamless transfer of RPC-XXX, should the need for relocation arise. In the event of a breach, RPC-XXX is to be re-contained as follows:

Multiple replicas of RPC-XXX's containment cell are on standby for use during repair or recontainment. Personnel are to follow recontainment protocols during transfer of RPC-XXX between cells.

One side of the replica containment cube, should remain unattached from the main structure by default. This side is to be securely welded shut after RPC-XXX has been successfully re-contained. It is noted that RPC-XXX is very sensitive to high frequency sounds, thus the use of loud speakers can aid in its recontainment. In the event of a containment breach, personnel are to utilize high-frequency audio to coerce RPC-XXX back towards the entrance. All personnel must be equipped with full PPE to prevent contact with the anomaly.

Personnel entering the chamber must wear modified hazmat suits to prevent RPC-XXX from touching them in the event of a breach during entry. The entrance to the containment chamber is disguised as a concrete slab located at the south-east corner of the cell. This disguised entrance should be inspected regularly to ensure its concealment remains intact. Merged with previous paragraph.

RPC-XXX at first glance resembles a ball of mist, estimating to be 16 meters in diameter. RPC-XXX can move up to 64 kilometers per hour when pursuing a target, RPC-XXX will remain in a comatose state unless an individual with sentience is within a 6-meter radius of it or is within line of sight.

RPC-XXX resembles a visible aerosol suspended in a spherical shape 16 meters in diameter when at rest, comprised of water droplets. While typically stationary, RPC-XXX manipulates air currents around itself to change positions, usually when in pursuit of a target, recorded at up to 64 kilometers per hour. RPC-XXX engages in this predatory behavior should it detect a living thing. How RPC-XXX perceives is unknown, although it usually is only capable of sensing movement in close proximity to its suspended particles, as it appears to disperse itself across a greater area when attempting to locate a target.

The section in blue is just a suggestion. It's not ideal but I think you should add something like it to at least address how a ball of vapor senses the world around it.

To which RPC-XXX will begin to actively pursue the individual, its behavior in pursuit will vary, as it has been observed to be extremely patient and calm while hunting. But in other cases, it has been observed smashing, beating, and throwing objects out of its way to pursue a target. It is noted that if RPC-XXX is "not in a good mood" during a pursuit, it will grow angrier if the pursuit continues for over 3 minutes. RPC-XXX appears to have kept its previous victims alive and trapped within itself, forever in a state of constant decay and regeneration, instances of these victims are labeled RPC-XXX-1.

RPC-XXX's behavior alternates from a slow, consistent hunt reminiscent of pursuit predators, or a rapid burst at its full speed akin to an ambush predator in nature. Generally, RPC-XXX only engages in the latter when it has been deprived of sustenance for long periods of time. Failure to capture a target with these bursts of speed in a short period of time, typically 3-5 minutes, results in more violent behavior from the anomaly, using its manipulation of air currents to destroy and launch objects around it.

As for RPC-XXX-1: It's pretty edgy. I think its odd to have it mostly seem like an animal but then "it traps people in itself and digests them FOREVER!!". Like does it just live off of them suffering? The whole section could be cut out it's just so strange. I would replace it with how it does capture people and digest them, but maybe it's usually pretty quick. BUT, it slows down and digests people slower if it hasn't gotten a lot of food. So when its in containment, the last person it caught is stuck in there, alive, being slowly digested because the anomaly is worried it'll starve in those conditions.

Depictions of RPC-XXX-1

These images are really silly looking and they don't contribute to the article. Out of universe, they don't look good. In universe, why would the RPC Authority put these in a document? If they're not real photos and they're not well made, why include them? Cut them out.

The main factor of intrigue is obviously the RPC-XXX-1s. However, they're introduced in such a way that kills offf any momentum that could have been had. Take this for example:

RPC-XXX appears to have kept its previous victims alive and trapped within itself, forever in a state of constant decay and regeneration, instances of these victims are labeled RPC-XXX-1.

This sentence presented from the Authority's point of view describes exactly what RPC-XXX-1 is without any subtlety. By doing so early on in the article, the rest just becomes repetitions of what has already been said. How did the Authority figure out the "constant decay and regeneration" part anyways? I suggest changing this bit of the description; make it make the reader raise suspicions about something deeper, instead of telling them that straight up.

The "RPC-XXX-1" collapsible is a mess. Only the first paragraph is actually about -1. The other two are more about the main anomaly.

I might have missed something, but I can't make sense of the first addendum form a narrative standpoint. What does it actually achieve, in terms of telling a story?

The first and second addendum belong in the description instead of as addenda.

The two audio logs are disappointing. This is because the reader usually expects some kind of reveal from the ending of the article, and such a reveal can be all the more impacting if it comes in the form of an audio-log. Unfortunately, the audio is nothing but ambience. Therefore I believe that if you included the audio logs closer to the middle of the article (possibly around the description?) It could help with theme building.

All in all, the article needs more subtlety to create intrigue. Right now, since the main element is outright told to the reader, the rest of the article feels like a repetitious chore. I do however believe that the theme building is great, especially with the pictured and audio logs (which need to be repositioned). With a bit of work, I think this could turn out pretty great.

reported to Site Security for repairs.

I don't think "Site Security" is a common referral. I suggest reading the containment division hub http://rpcauthority.wikidot.com/containment-hub and finding a more suitable group.

Ectypes are rarely encountered in the field, but when spotted, they cannot be distinguished from humans by any surface-level examination, but they do have notable chemical, neural, and psychological differences from humans.
To

The commonality of Ectypes is estimated to be low, roughly [1 in #]. An accurate estimate of the Ectype population is hard to come by due to their collective secrecy and Human physiological mimicry.

The limbic and autonomic system, while reminiscent of the human body in structure and layout, is approximately twice as dense and capable of fine motor control in each part of the body.
To

Deviating from the Human body's structure and layout, the limbic and autonomic system is approximately doubled. Capable of exercising fine motor control over every organ and limb.

The regions of the Ectype’s brain are nearly homogenous and far more complex than the cerebrums of most species- meaning they are fully capable of operating their body with less than five percent of their brain intact.
To

The Ectype’s brain is nearly homogenous, lacking distinct lobes or segments. With a generalized central nervous system, an Ectype can operate their body with less than five percent of their brain intact.
Note: If it's homogenous and can survive even the worst fatal injuries, it should lack a cerebrum.

The cells of Ectype bodies feature DNA in their imitation of humans, but it appears to be vestigial. Given that the methods for an Ectype's survival, healing and reproduction are anomalous, Ectypes do not use DNA in their biological functions.
To

Ectype cells feature Human DNA, but it appears vestigial. Given that the methods for an Ectype's survival, healing, and reproduction are anomalous, Ectypes do not use DNA in their biological functions.
Note: You should specify the nature of this anomalous ability that somehow permits their body to develop in ways outside of the DNA's preview.

Further examination of Ectypes has proven impossible given this barrier to studying their biology. Additionally, there are few signs of cell decay in Ectypes.

Note: I'm unsure how "further study" of Ectypes is impossible, nor precisely what it refers to here.

To the knowledge of the GRPC, the only known method of neutralizing Ectypes is through elimination by force.

Further, it is difficult to discern them from a corpse as well- there have been several cases of GRPC personnel attacking and neutralizing an assumed thrasher, believing it to have been a normal human that they have accidentally identified, only for it to animate once more and escape.
To

It may not be easy to discern a Thrasher from a regular corps. There have been several cases of GRPC Rangers firing upon an assailant, only for it to animate once more and escape.

Thrashers are often utilized for impersonation of personnel, meaning that the bodies are often possessed shortly after death by suicide, as subterfuge is increasingly difficult should the identity be declared dead.

Note: You've explained that they possess the corpses of those who committed suicide. This segment has been posted after the paragraph about them pretending to play dead. It can be removed or moved before the section above in the paragraph order.

Ectypes are capable of imitating the full range of emotion and behaviors perfectly among all observed sapient species, but are notoriously sociopathic and believed to be non-sapient. Notably, Ectypes are incapable of recognizing themselves, such as when presented with a reflective surface.

Ectypes can imitate a range of emotions and behaviors perfectly among all observed sapient species. However, behavioral analysts hypothesize Ectypes are notoriously sociopathic. Unable to recognize themselves, such as when presented with a reflective surface, they are classified as a non-sapient species.

A collection of the technology acquired via occult interstellar travel known as the 'Grey Book' was created and slowly introduced these alien processes into the German scientific community.

The Red Wake then provided detailed information on Earth's worldwide capacity to respond to alien invasion (the 'Schuyl Report') which in combination with Ectype saboteurs allowed for the invasion to be far more effective.
To

It is unknown exactly when The Red Wake provided detailed information on Earth's worldwide capacity to combat an alien invasion (the 'Schuyl Report'). All that is known is at some point, the 20th-century Ectype saboteurs allowed for the invasion to be far more effective.
Note: These Trans Humanists Necromancers who controlled a good chunk of the Western world's technological center turn tail and betray Humanity for aliens. This information deserves a more in-depth explanation than "allowed for the invasion to be far more effective."

Ever since the invasion, reports of Ectype and Thrasher activity in various civilian and military installations have only increased over time. Due to their past control of Rangers and other personnel, the extent of the Red Wake's knowledge regarding GRPC is unknown but severely compromising, as multiple spacecraft and space stations have been lost to Thrasher sabotage.

Note: Go more in-depth on "past control of Rangers and personnel." Let's learn how dangerous the Ectypes are by getting a feel for the damage they have done to the Rangers.

Note: I understand that Ectypes can possess the corpses of the dead by turning them into a Trasher, but how can they replace a dead staff worker? Wouldn't it be more apt for them to screen new Human cadets for signs of being an Ectype?
