Animal Survival Horror Game (some mature content)

[ChickenFetus]

For the past couple years I had been working on two prototypes for game concepts I had. One was an ecosystem sim/world-building game in Unity, the other was an animal based survival horror (which I used "Cat Story" as a placeholder name) in RM VX Ace (however, I'll probably switch to Unity for the actual game)

I made these to get people's thoughts and opinions (e.g concepts, mechanics, art and etc.) before deciding what direction I want to go in with a more serious project. I've also been doing a lot of practice with pixel art and wanted people's opinions on that as well.

I didn't bother adding a download link to either since I assumed no one would be interested in actually playing either prototype. But if for some reason someone is interested in trying the Animal Survival one (the ecosystem sim is not really in a usable state) let me know.

*Warning: Some violent, morbid and creepy content in this one. This is not a child friendly game despite the cute kittens.

"Animal Survival Horror Prototype"

Cat Story A Survival Horror About Animals

Mama Kat used to live a peaceful life family: her owner and her owner's other pets. She had everything she needed, and the only thing she had to worry about was her brother and the family dog annoying her. Now the humans are gone and the town pets are either dead or want Mama Kat dead. All that remains of her family are her three young kittens. To keep what's left of her family alive, she must hunt and avoid being hunted.

But feral dogs, and a crazy territorial calico, are not the only creatures she has to fear. In absence of man, strange and terrifying beasts have begun to arrive. Some from the cold forests of the north, others from the dark ruins to the south. These deadly creatures now fight to claim rulership of this land, with Mama Kat's family caught in between.

This is a prototype for a game concept I've wanted to make for a long time: A post apocalyptic open world survival horror game about animals trying to raise families in a savage land where man has left behind ruins... and nightmares.

• A strong emphasis on creature interactions in a dynamic ecosystem where the player is small and not special to the world. Each creature has it's own ways to hunt or avoid being hunted (the prototype has 32 different species of creatures, 12 of which prey animal for the player)
  
• Many creatures are individuals with unique personalities.
  
• Various habitats and regions that require different playstyles having different dangers and prey sources.
  
• The animals, especially the player, can use foliage and their environment to their advantage. Such as hiding in the grass or using trees to escape predators.
  
• A combination of artstyles such as pixel and photomanipulation

"Other Influences"

Silent Hill, SCP Containment Breach, S.T.A.L.K.E.R, Resident Evil, Isolation (a 2005 Irish film), various flash horror games such as Exmortis and Vorago, and various rpg maker horror such as Snow Drift.

This prototype was made with RPG Maker VX Ace (although I did also use XP assets, I own both. Plus I purchased several dlcs during a steam sale). However, for actual game I'll probably switch to Unity and re purpose the code from the above ecosystem game. The plot of this prototype was taken from a story I originally wanted to write as either a novel or webcomic.

Although, I have been considering dropping the plot in favor of a more something more generic and less linear (although I still do want to continue Mama Kat's story somehow in the future). I find making linear storied games, and cutscenes, to be less enjoyable to make than more procedural worlds and stories without cutscenes.

However regardless if I keep the story or not, I do intend to add other playable animals. Mama Kat's story basically being the "campaign mode" so to speak.

Playthrough and Videos

Content Hidden

I made a playthrough video series (as well as videos of cutscenes and bonus content). Since the playthrough was kind of long, the spoiler below only has part 1, 4 and 5 (and the extras). They were shorter while showing off more atmosphere and gameplay. The rest of the playthrough series is on my youtube channel and demonstrates other mechanics and atmosphere. Credits for resources used to make the prototype are in "Cat Story part 7" of the playthrough.

Gameplay Mechanics

(Kind of long, see above for shorter synopsis)

Content Hidden

• A dynamic ecosystem where the player is neither special nor important. Each creature tries to hunt or avoid being hunted. For example, at 6:20 in Part 4 of the playthrough, an owl catches a mouse that mama kat was stalking. Although in the prototype, rats and snakes will also hunt mice while dogs and wolves hunt rabbits. There are also occasions where player can find dogs and wolves chasing animals such as deer and foxes (although these are preset events, I want in the future for it to be more procedural). There are also cutscenes, and preset events, of animals fighting for food and territory but again I plan for that to be be more procedural with actual combat between npcs.
  
• Many of the animals are individuals with personalities. Among mama's kittens: the white is often the first to greet her, the black loves to play chase. Both black and white kittens sleep on a cat bed. The tabby kitten is a lazy bum who sleeps wherever  it's standing. Among the dogs: the brown is the slowest yet most powerful, the white is fastest, the husky sees farthest and the black/grey dogs can track mama's scent even if they haven't seen her.
  
• Each prey animal has a means of escape other than just fleeing and none (except bugs and certain abominations) are helpless to predators.  Rodents can run into holes, birds fly off, squirrels can climb trees and buildings, bullfrogs swim away and etc. Rats will bite when cornered and rabbits can deliver powerful kicks if caught.
  
• Most games have ambient noises that are not made by ai, but rather are simply background noise. But Cat Story has birds and frogs that let out calls both for atmosphere and to notify player that prey is in the area.
  
• Strange objects and edible non-animal creatures that can do things for player that ordinary wildlife cannot (e.g regenerate health, increase stats and etc.)
  
• Various habitats and regions that require different playstyles having different dangers and prey sources. Players will have to decide which areas are safer and offer the best food. Prey and dangers vary upon time of day as well.
  
• The animals, especially the player, can use foliage and their environment to their advantage. In the game mother cat and other animals can use tall grass and bushes to hide from prey and predators. She (and owls) can hide in trees as well. To escape many predators, mother cat can climb trees while squirrels can also climb buildings.
  

However, I'm not very happy with how tree climbing came out in Cat Story. But I'm not sure how else to set that mechanic in a 2d overhead setting.

• Animal combat is more than just smacking each other around till one party dies. In real life predators try to restrain prey while attacking. Prey try to keep enemies at bay (e.g running away, threatening if cornered or striking if caught). So I gave mother cat the ability to grab prey and bite. However caught prey (especially rabbits and rats) will try to strike at her and make her let go. Mother cat can use her claws to keep predators away if she's cornered.
  

(In the past predators in Cat Story could grab mother cat as well and she would have to use her claws to keep escape. But because of bugs I removed it. The basic mechanic of predators grabbing the player and the player having to thrash or attack is still something I want to do in the future.)

• Conversely, among rival predators that are evenly matched there's often more display and intimidation than actual combat (aside from biting exposed rears).  Although there's no actual npc vs npc group fighting, there are cutscenes and events involving groups of animals fighting. Most came out bad, unrealistic and not how I wanted (I still loathe the cutscene with the grey dog being killed for how unrealistic and corny it came out). But I thought the dogs challenging the creatures over the deer carcass in part 5, and the dog pack surrounding the wolf (part 2 at 2:40) were okay and conveyed what I envisioned in my head. They were both inspired by videos I saw of groups of wild animals fighting (grey wolves vs bears or domestic dogs, african wild dogs vs hyenas, hyenas vs lions). Although I probably should have added more rear biting that was common in those videos.
  
• Photomanipulation: When I was younger I played a lot of flash horror, many of which utilized photo-manipulation (especially Exmortis). But I also really loved Omega Flowey from Undertale. So I decided to try photomanipulation for a game myself. The image I used was of uncooked mutton being sold at a market. While I like how it came out, I'm not sure I'll do it again in the future. I'm not sure how to utilize photo-manipulation in a 2d overhead game without getting repetitive. Plus, even if I do photo-manip again, I don't think I'll use meat again for a source image for various reasons.

All resources were either made by me, RTP from VX Ace and XP (I own both), purchased DLC or resources free for non-commercial usage (mainly scripts, music and animal sound effects). No animals were hurt in the making of this prototype. The sound effects came from various sources online,  none of which stated animals being harmed (for example, the dog death howl was actually just a slowed down puppy tantrum). If you know otherwise, please let me know so I can remove it. The photo-manipulation was made using an image from FLICKR of mutton being sold at a market from human consumption.

Although I probably will no longer work on the ecosystem sim for various reasons (but mostly because I assume animal survival would generate more interest), much of the code and concepts will likely be re-purposed for the animal survival game when/if I switch to Unity. Although the actual tools for modifying to ecosystem will no longer be utilized outside of debugging. But I figured I'd state what this was originally going to be nonetheless and see if people thought any of the concepts could still work in a survival game.

"Ecosystem Sim Prototype"

In the video above showed some features of a much older version of ecosystem sim I made in Unity (I have much more recent versions with better code, ui, day/night system but this version was the only one with functional AI). Unlike the animal survival one, almost everything here was made by me (but much of it is old and no longer used).

The basic idea was a more modernized version of Simlife (although I also took inspirations from Site B mode in JPOG, Zoo Tycoon, Wildlife Tycoon and StarWars: Gungan Frontier) or even something like Dwarf Fortress but building an entire ecosystem instead of a fortress. Some concepts I had were...

•  Ai that has dynamic interactions. For example, in the video the "Twerbivores" form mated pairs and work together to protect their offspring from predators. Carnivores stalk their prey because if they charge to soon they can run out of stamina and the prey can escape. Later versions of the game (not the one in the video) had pack hunters and creatures were only females engaged in parental care while males would kill offspring to bring females back into heat.
  
• Most ecosystem games I've played the only thing that influences populations is death by starvation and predation to "balance the ecosystem. While predation is important, it is not the only factor (plus the way most games have it set up, often predators consume everything and cause their own extinction). Plus death is not often the main cause of population decline when it comes to malnutrition, it's lack of reproductive success. In my ecosystem game, animals can only breed if they have enough nutrition. Evidence suggests that inability to reproduce from malnutrition (or stress) can be just as, if not more, important to animal populations than predation and may be the true source of population cycles. I also had plans for predators to be defend territories and kill rivals so as to limit population density or predators as is the case with many predators IRL.
  
• Not in the sim, but I wanted to include diseases and parasites which are also important in controlling animal populations.
  
•  Complex soil and flora that's more dynamic than is typical in most video games. In most games, plants are only scenery or, at best, intractable objects. In this game, they are just alive as the animals and have their own needs (e.g plants reproduce, require sunlight and moisture but can also die from drowning or overgrazing.) I also had plans for them to have defenses as real plants do, or utilize animals for reproduction (while the plants in the video produce fruit, it doesn't really do anything other than feed herbivores).
  
• Weather that influences the ecosystem (later versions have rain that effects soil moisture and players could set what kind of weather the ecosystem had such as monsoons)
  

However based on observations and research, I suspect interest ecosystem management game would not generate as much interest as survival game (and let's be honest, half the comments I see regarding ecosystem games is "I want to play the animal").

But I do plan to retool much of the ecosystem code I wrote into the survival game. Although plants and soil will not be as dynamic as planned, I still want them to be more dynamic than most games.

Sprites
Although the Animal Survival Prototype uses many placeholder assets, I added many of my own sprites (owl, deer, snake, humans and most monsters). Although I did not add any original environmental assets to that prototype, I have been practicing on making pixel buildings and foliage. I would appreciate your thoughts on the sprites I made.

 I've also considered doing fictional animals instead of real ones (this does not include monsters which I intend to be separate from animals).

While I imagine people would prefer real species, this would come with many difficulties that would severely limit gameplay and species amount. People (including myself) have much higher expectations for real animals, and making sure the design and gameplay adheres to the real thing can be a challenge (for example, finding specific sound effects for specific kinds of animals can be a difficult, sometimes almost impossible.).

The challenge with real animals would also mean the overall species diversity, and gameplay, would be FAR lower than if I did fictional ones.


Several directions I'm considering for fictional animals are...

• • Continue current direction with real animals. It's important to note that this direction would have FAR FEWER species and much more limited gameplay.
    
  • Fictional species that have fantasy powers (I always toyed with the idea of a game that's based on Steven King's The Mist where people play as the alien creatures). This would probably allow far greater freedom gameplay wise and allow for a much much higher species diversity. Design influences would be Half Life, Metroid and Wayne Barlowe's Expedition.
    

Something to note is even if I go with more of "The Mist" direction, I'd still probably have small things such as rats and bugs. It's also possible for me to continue with mama cat's story. Except instead of an ecosystem of real animals, it's an ecosystem of alien creatures.

• • A combination of real and fictional animals. Not sure how that'd work though. Possibly include some abnormal animals (e.g resident evil, rainworld, stalker, the isle)
