W40k first person horror game where you play as a tau human civilian in the middle of an invasion from almost every faction in the setting.
It plays like a mix between Alien Isolation and SOMA in which you are a noncombatant faggot who can't fight at all, so instead you have to solve puzzles, use the environment, and use tools to evade combat as much as possible because everything can kill.
You will have a chapter to lower your tension by introducing you to your family, friends, coworkers, neighbors and random people you meet in the city.
Then suddenly all hell breaks loose.
You now have to hide, get shit you need to not die, bring as many people from xenos to other humans to a possible shelter, and either try to escape, get evacuated, or find a more safer place to bunker down and hope shit passes.
I want to make it as inmmersive as possible too.
Also, i want to show just how fucking scary everything throw at you is.
Space Marines and orks charging at high speeds, posse's of kriegers just lynching people and setting them on fire, wizards doing wizard fuckery, Tau soldiers with PTSD from the 4th expansion just breaking, nids being NotXenomorphs, Dark Eldar and Emperor Children doing their best to do body horror, mechanicum being scary motherfuckers.
Have all the silly horror from W40k just getting throw to a civilian running away with food and a random alien baby he just found next to its parents in the middle of the street that look like some crabmen that were running the Carpet store 3 blocks from your house.
The Eternauta, but with a bigger, bloddier clusterfuck.
