📋 About This Mod

Mental Stability System is a relatively complex mod that introduces a Sanity mechanic into the game. Various in-game events and factors will affect the player's sanity, both positively and negatively. Once your sanity worsens beyond a certain threshold, you will start hearing voices and even experience hallucinations. The voices will sometimes talk nonsense, but other times they will be directly talking to you or reacting to your actions and other things happening in game. The worse your sanity gets, the more intense, aggressive and frequent the voices become. That's the basic idea, anyway. But if you want to know more, keep reading this description. There's also a thorough guide talking about pretty much every feature of this mod in the Articles section. It's not necessary to read it to understand the Mental Stability System, because I'd say pretty much everything in this mod is intuitive, but it's still usefull if you want to know the details of how the system works.

[]The Voices - As mentioned above, you will start hearing voices when your sanity gets bad enough. There are basically 3 main voices that you will be hearing (with some others chiming in here and there) with almost 400 unique voice lines. And all of them are voiced by real voice actors that I hired specifically for this mod, no AI was used.

[]Sounds - Alongside the voices, you will also sometimes be hearing various creepy sound effects. There are around 150 unqiue sound effects in total.

[]Visual Hallucinations - If your sanity gets bad enough, you'll also experience various visual hallucinations, but revealing their specific nature here would kinda spoil the experience. If you find out they're not your cup of tea, you can turn them off in the config file.

[]Cyberpsychosis - Introduced in version 2. 0, this feature makes it so cybernetic implants affect your sanity. If you have too many of them, you can start experiencing cyberpsychosis during combat (inspired by Edgerunner perk from Cyberpunk 2077).

[]Antipsychotics - This mod also introduces a new aid item called Antipsychotics. As the name suggests, it is there to help you manage your degrading sanity and keep the voices silent. They come with scripted LL integration and are craftable.

[]Self-contained - Basically the entire mod is self-contained. By that I mean almost no vanilla records were touched and it should be compatible with pretty much anything. (There are some minor caveats though, so check out COMPATIBILITY near the bottom of the page.)

[*]DLC included - The mod was made with all DLCs in mind, so the voices will also be reac
