Accidental Innuendo: At one point, on the Nintendo Switch version of the game, the icon for it looked... well, a lot like a certain form of female anatomy, if not an anus. Made of monster meat. It was eventually changed to look more like that of the box art.
Alternate Character Interpretation: Is the creature just another Generic malevolent-for-no-reason monster, or does it just want to escape and take revenge on the beings who imprisoned it for so long? Also, when it escapes, is it bent on world domination, or does it just want to hide and be left alone?
Demonic Spiders: Soldiers with flamethrowers. Not only are they armored and have an electrified shield in front that will shred your health if you touch it, they will use a mid-to-long ranged flamethrower that deals rapid, constant damage, sets the monster on fire and kills it quickly if it cannot find water. To add insult to injury, they also cannot be eaten for biomass due to their armor. Stealth is practically required when facing any amount of these.
It seems odd that there are two DNA abilities called Parasitism, one of which allows the monster to take over humans, and the second allows the monster to transform into a human to escape the facility. Then, you realize that the second is essentially a perfected version of the first, being able to fool human and DNA scanner alike. In fact, one can test this in the room with the second version: using the first by piloting a human fails a couple of the five checkpoints of the scanner, while the second version passes all five.
In the third flashback, it is revealed that the human character we have been playing as was killed by the creature between the second and third flashback, and the creature has assumed its form to try and escape. This means that for the duration of the game, the powerups are actually our body parts and we're making ourselves whole again.
The third and final flashback generally makes a lot of sense considering the twist. A turret attacks you out of nowhere, and you're forced to shoot it down with a stun gun. There's also a body floating in the biopool near where you start. This is the only flashback to feature armed enemies at all. Considering you're actually playing as the Monster here, the violence makes sense. The corpse was likely dealt with before the Monster took over the researcher. The turret wasn't attacking because it's gone haywire, it was attacking because it detected the Monster inside of the researcher.
Goddamned Bats: The small flying drones are annoying because they're fast, flying close-range Collision Damage combatants spawned in packs by a drone factory machine, and you often encounter them when you are in the wrong size and/or in tandem with soldiers or mechs. The Monster's small form is actually the best at dealing with them due to the fast-firing Arachnoptysis nullifying their movement and Collision Damage, but the allies they're paired with can dispatch the small form quickly. The large form's Harpagorrhea is also useful for impaling and shredding them.
is a love-letter to horror soundtracks of The '80s and The '90s.
