The Stars, They Scream

Brainstorming Screaming Stars

What are the Zombies called?: This is where I decide what to officially call all of them.

• Deadforms
• Phantoms
• Necroforms
• Darkforms
• .

Name ideas: Names for the setting. Planets, space stations, ships.

• Grave Star
• Star Screams
• Recombine

Tormentor: An advanced Deadform, seeking to 'torment' the MC as they go along. They do this by awakening other Deadforms, perhaps even creating new ones as an advanced form of infector. It avoids direct combat with the MC, even going so far as to retreat when necessary. It's large, yet it slinks through the tight corridors. In open spaces, the MC would have to avoid either it or its minions. Perhaps it becomes annoyed with the Gunship also pursuing the MC and attacks it, leading to both being destroyed.
Gunship: A gunship, likely piloted by an enemy human faction to the main character. It would hunt them down with prejudice, using its onboard weaponry to impede the MC's progress. It may also have a hacking ability, able to lock off areas and otherwise interfere technologically. After a certain time, the Tormentor finally strikes at it, and the MC can escape or perhaps is roped in unintentionally as the two duke it out.

Story and Gameplay

The Starts to all this

Cemetery World: A planet turned into a cemetery. It contains the remains of millions, if not billions, of corpses. The curious miners, not knowing of its history, see it only as valuable resources to take. They would uncover a cursed artifact, turning the dead into monstrous creatures through demonic energy.
A Sci-Fi Vampire: This is an exceptionally long-lived alien, who uses energy transference technology to survive. This life draining energy steals other's lifeforce... somehow, leaving them a drained husk and the drainer youthful, if not unintentionally taking on characteristics of its victims. Possibly a stargate like idea, where someone keeps people in a perpetual medieval age for them to mine resources and feed his essence.

Characters

(Main Character) Let's Punch it: This man isn't afraid of the infection. He punches the zombies with no regard for himself. He may be immune because he isn't afraid. All those who have fallen have fear somewhere in their hearts.
I shot my leg off: A person was captured by a larger monster, probably some sort of dragging tentacle. Wanting to avoid a horrific fate, this person either shot their leg off since the tentacle was too well armored for their gun, or they managed to hold on somewhere and let it be ripped off. As expected, they had to figure out how not to bleed out from the lost leg, and either found a way to cauterize the wound, or have since bled out in another death among the many.
Talon to the chest: This survivor survived a direct stabbing to their chest. They cut off the offending limb, leaving it in to prevent bleedout. However, the talon would mutate, corrupting the survivor. It turned them into a semi-smart zombie, probably the wound becoming a glowing weakspot to shoot.

Weaponry

Stun, Shock, Burn Shotgun: A gun that acts like a shotgun, easily tearing through recombined flesh. It can be upgraded to apply a slowing effect, be more explosive, even stunning its victims.
Flamethrower: A flamethrower, meant to remove oxygen and burn out pests. It becomes incredibly useful now as a means to permanently deal with the new flesh growths. However, some of the monsters have combined themselves with flamethrower tanks, which then are thrown or charged into the player in an attempt to catch them on fire.
Security Rifle: A futuristic rifle that has a rapid rate of fire. It isn't great at direct destruction, especially against the recombined, but shooting their glowing weakspots works well with minimal ammo loss.
Powered Limbs: Limbs that are powered. They have lights on the specific limbs, probably at least the arms. These lights depict limb health and likely limb power.
Put some force behind it: His arm swings and boot stomps can be upgraded to do an Area-Of-Effect attack, expanding their attack potential even further.

Monsters

Relentless, Immortal: All created necromatter must be destroyed, or it continues to live. While dismembering it does slow it down considerably, it all can move. The head, the limbs, the torso are still alive and desiring to kill and expand infected matter.
Glowing Weakspot: These glowing spots on higher forms allow for quick regeneration. Shooting them releases tentacles, which quickly scour the environment for objects to use. Necromatter found in this way is quickly absorbed, healing the higher form and often growing a new limb. Often combined with the near-indestructible material making up the body and limbs of a higher form, meaning in order to take them down, one needs to hit the glowing spots, often at joints.
Necromatter: To us, it's gross, it gets into everything, and it slowly corrupts everything it touches. To the Deadforms, it is the beginnings of home.

Cysts

Rot Nest: While the necromatter does spread on its own, this is a creature designed to direct and forward it. Its long tentacles stretch like plant roots across its environment. Killing it does slow down the spread, but there is little stopping another from forming or being reawakened.
One of its direct minions are zombies with massively increased lungs, meant to slowly but surely suck in clean air and breath out something more toxic.

Bits

Nothing is too small: The bits and bobs of Deadforms. Killing them, stopping their larger bodies, doesn't mean they stay down. These will scuttle and scratch their way towards new victims. Only a cleansing flame puts anything down for good.
Spawners: Like the normal slasher creatures, only they have a sack of newer, smaller creatures ready to go.
Head Crawler: A head that crawls. It can be seen on combiners, larger creatures composed of a mess of many bodies' limbs. Its goal is to find a new host and overtake it, removing or joining with the original head and controlling the body.
Active Limb: An arm or leg that was infected. It can move and function on its own, though it can reattach to active bodies.
Slug Torso: A torso and mostly the 'trunk' of a human, often without limbs or a head. It can move on its own, often in a slug-like fashion, though it is prone to mutation.
Swarmer: The smallest form of the menace. They crawl towards uninfected, attempting to overwhelm with sheer force, possibly even infecting and overtaking a new host. There are a few forms dedicated to carrying packs of these swarmers, ready to be unleashed as needed to recombine new flesh.

Uncannily Human

Recently Turned: These are the Deadforms wearing masks of humans, mocking an inferior species. Rarely do they fool for long, but sometimes, a second is all you need.
Recombined: A collection of several Active Limbs and Head Crawlers, anchored to a body. The body is heavily overgrown with dark tentacles, anchor points for the limbs. The creature is tall and lanky, partially a commander, partially just a walking, slender horror.
Drained/ Hungry: Those who ate Necromatter, causing their digestive systems to turn bad. They die painful deaths, often eating what they can find, often to their deaths, only to be revived as Hungry. Drained are in the same boat, but they are victims of the energy transference. Barely anything is left of them, though they are still mobile, able to attack and only feeling hungry, desperately seeking to regain what they have forever lost. While they are often mad with rage, a few who can be swayed will attack the energy vampire.
Arm Talons: The footsoldiers, the main mutants of the recombined. They are humans with their arms mutated into slashing talons. There are many varieties of these arm talons.
Main variety just are walking zombies with slashing arms. There is an armored variety where instead of larger talons, it instead has hand sized sharp claws used more to pull things apart rather than generally slice.
Twitchers/Fastbois: Arm Talons that had stasis modules on them, often scientists, security, or military. What this means now is that they are incredibly fast now. The normal stasis does not work on them anymore, but their stasis module can be shot to emit a one-time stasis pulse, slowing down itself and anyone near it.

Alien form

Close to the Stars: These forms are clearly alien, often more powerful than simply humans recently recombined.
Spider Crab: This is a horrific monster that bears resemblance to earth Spider Crabs. It has around 8 long, slender limbs it uses to balance itself and move its tight, shrunken torso. Its torso is likely based off a ribcage. It has talon pincers, sharpened bone slapped together resembling crab pincers, easily able to chop off a limb. For ranged attacks, it has combined with a Tentacle Spewer, which erupts tentacles from a somewhat armored body to throw various objects from bone spurs, exploding ammo, even sharp world objects at foes.
Armored Petal Walker: It has lower legs, but the main draw is its armored flower-like structure. The outer petals are incredibly resistant to weapon damage, protecting a soft inner core. The armored petals are the strongest, so the best idea is to ruin the legs or somehow pry open the flower, hoping to not get chomped in half or whatever horrors lurk within.
Claw Brute: A giant mass of several bodies turned into a brutish creature. These are made after several Necroforms have been destroyed, causing the hive mind to adapt, creating a large, harder to destroy brute. They have fat arms that end in sharp arm talons, clearly taken from slasher forms. If an enemy is too far away, it opens itself up, revealing a few guns that have been crudely integrated, and fire somewhat aimed, though relies more on volume of fire rather than accuracy.

Synapses

Synapse Overview: The largest and smartest of the Deadforms.
Giant C-Fly Mutant: Likely the final boss of the game. It has several glowing weakspots which must be destroyed. Its main limbs are near-indestructible, hence needing to destroy the glowing weakspots. When its spots are destroyed, it will sprout tentacles which will grab any lesser monsters to turn into a new glowing spot. However, there is a world object, probably a lightning rod, that will zap the rod, causing massive damage to the creature.
Another idea is this object is easily manipulated. Getting it to reabsorb it means you can tear it apart with your powers.
Absorber: A higher form of the infection of Darkforms. By releasing its glowing energy, it quickly pulls in whatever it can, necromatter and other items as well. It quickly regenerates and gains new armor or weaponry.
