Recruits guide to space exploration, chapter 1, paragraph 1:
Always wear shades, space has no atmosphere and is therefore very harsh for your eyes, engines usually burn very bright, and getting blinded by the flash of an exploding space vessel is crippling in combat situations, it also makes you look very awesome, so always wear those god damn shades.
You are a space pilot, you are a courier for both the space goverment and private corperations, delivering messages and secret cargo to various institutes, anything from fetuses to ISBM missile launch codes. Yesterday you were carrying a very important package for [REDACTED], today, you are in your space ship, with all systems failing, a firery ball towards Dust, the sister planet of Udo, rumored for its terrifying alien life, you must attempt to land it and keep the package safe! Its important!
So you crash landed, theres no way to get off here, you have set up your emergency equipment and sent a distress signal to a orbital communications node belonging to [REDACTED].
With your space ship crumbling to rust and your equipment breaking, you return to origins, breaking off a stick or a rock to defend yourself with, against those horrors lurking out there, those horrible beings that crawl out of the biomass pools to torment you!
@ is a concept of mine, a first person low grade graphics "shooter" set on a randomly generated planet, with randomly generated beings, everything but the terrain would be physics based.
At its core it would be a 3d evolution simulator, around the planet "shoggoth pools" are scattered, every ingame morning, the game would spawn randomly generated creatures to float in the pools, a current would push them out to the side, all the organisms, at spawning has a randomly organised neural net of random ammounts of cells and connections. Through natural selection, i.e ability to get to the food/light/air and defend itself, organisms would crawl, swim, fly, whatever out of the pools into the real world where earth minerals, fresher air, tasty other organisms/the player resides.
Some organisms would just be light and carried away with the wind to settle somewhere and grow into a colony, like fungus, some would crawl to eat theese organisms, some would chase them and another to chase em all. The player could for instance break off a branch/arm/whatever to use as a weapon, egded things could be used to reshape other objects physical properties and thereby making utilities. Using theese things and a bit of sticky dead shoggoth slime they can stick it together to form structures, tools, machinery, anything they wish. There would be various dangers, such as carnivorous creatures, vicious acid rains, meteors and other assorted crap raining from space, including rescue ships. Each month, a rescue ship would attempt to save the player, but a mysterious force would always mess it up, only way to escape is by repairing your ship yourself and flying away, or death. Theese rescue ships would be mostly useless(depending on the player) metal scrap, with some bits and parts useful, like survival equipment, spare parts to repair your ship with, or maybe medical supplies like cybernetic replacement limbs. The player itself would be treated as much as an organism as all the other organisms, only difference is that, instead of a neural network, its a player that controls limb movement, like organisms, the player would also have DNA, and by entering "strange" shoggoth pools, the player mutates, with various beneficial/!!fun!! effects. In the end, if the player dies in some way, or they get themselves off that damned planet, their score would be submitted to a global highscore, keeping mood and health up gives score, surviving for days gives score, death itself divides the score, other than that, should the science kit survive the crash, the player can use various analyzers to capture information about various organisms, and even record their gameplay, reverse engineer alien artifacts dumping down, all theese things, but the videos will give "science" points, the videos would be viewable by other players, they can then vote up or down based on their observations.
So this sums up to:
Evolution and physics simulator
Physics based combat game
Construction sandbox
Survival game
Arcade game
Spacecraft crash landing simulator
Fakeedit: I also had this wonderful idea: Multiplayer
Rescue vessels could carry sleeper pods with the rescue crew, theese things would be very fragile, and most of the time they would just be destroyed only leaving a bit of DNA sample, if the player can repair and power up a sleeper pod, you could pull a person out of it, allowing a friend or two to join in.
