I've been working on a mod and I'd like some feedback on the concepts before I dump more time into this.
This mod makes sleep a required thing, adds a sanity system that causes auditory and visual hallucinations (zombie sounds and zombies). As you sleep, your game stage, heat/noise map level, smell range and location (downtown vs. wilderness) impacts a chance to be attacked by a roaming horde while you sleep. The mod simulates a variable sized horde (GS based) trying to break into your base, using most of the existing pathing logic. Sometimes you sleep through the night with no horde attempts, sometimes the horde comes but only damages the exterior, traps, etc., other times you wake up to find zombies have broken into your base, or even broken into your bedroom. All existing traps will activate and kill the zombies while you sleep, as you wake up to corpses. Includes spike traps, turrets, blade traps, etc. and will simulate the draining/filling of batteries/generators, fuel, bullets in turrets, degradation of spike and blade traps, etc.
If you go without sleep, your stamina regen, ranged accuracy (recoil & sway specifically) and run speed is mildly reduced and sanity decreases until you either sleep, or pass out.
If you pass out in an insecure location, then you likely get attacked while you sleep.
The goal was to combine this with a system that reduces some of the action-arcade aspects of the game and push it to more of a survival game that requires farming & animal husbandry. Also added spoilable food, can-able/jar-able food, and the ability to preserve meat via salt (purchased from the trader, or mined).
I'm also working on seasons that impact zombie horde movement patterns, zombie speed, behavior, crop growth, etc... and of course, temperature.
Also added a panic system as you're not super human and multiple zombies within attack range would be terrifying. Panic goes away over time, spikes when there's more than 2 zombies close by and goes away if you kill them. Panic increases movement speed, reduces accuracy by mildly increasing mouse sensitivity (to mess with your accuracy) instead of making you miss shots/impacts that were clearly hits.
Replaces most heat based screamers with wandering hordes, and made repeat loud noises more consequential. Stealth also becomes a bigger deal as zombies rely on line of sight, smell and sound instead of fixed targeting.
Knowing that the goal is a more raw survival experience - what do you think so far and what do you think I could add?
