Get instant access and start playing; get involved with this game as it develops.

What the developers have to say:

Why Early Access?

“To collect player feedback on game mechanics, balance the game and fix bugs, while working on a story mode.”

Approximately how long will this game be in Early Access?

“About 1 year. I used to be working on it in my spare time but in March I started doing it full time! Progress may still be quite slow as I am just one person though. I started work on the original Survivalist in 2009!”

How is the full version planned to differ from the Early Access version?

“The aim is to include a Story Mode similar to the original Survivalist, add more polish and optimization, fix bugs, and incorporate player feedback.”

What is the current state of the Early Access version?

“I've implemented Sandbox Mode (a procedurally generated map and story) with melee and ranged combat, stealth, hunting, farming, chickens, crafting, building, dialog, community building, relationships, alliances and quests that give you long term goals. It also has online co-op and good support for mod-making via the workshop.”

Will the game be priced differently during and after Early Access?

“Once I feel Sandbox mode is sufficiently polished I think I will raise the price a bit, and it is likely to be more expensive again once I've completed Story mode and it leaves Early Access.”

How are you planning on involving the Community in your development process?

“I mostly use news posts and the Steam forums. The community have set up a Discord Channel which is pretty active. If you have a specific bug to report the best thing to do is email me at”

About This Game

Survivalist: Invisible Strain is an open-ended game about building a community after the collapse of civilization. You can recruit survivors by making them like you, or respect you, or fear you. You'll need to keep them warm, keep them fed, and build a settlement to keep them safe from zombies, looters, and whatever else is out there. Use stealth, weapons, or words to achieve your objectives. Currently it uses a randomly generated world, with a story mode to follow later.

This is the sequel to Survivalist (but you don't need to have played it to understand what's going on).


Talk to anyone

All living characters in the world have names and personality traits. They remember your actions, and their memories affect their mood and their opinion of you. They have their own lives: gossiping, eating, sleeping, keeping warm, working and fighting. Some will give you quests; it's up to you how or whether to complete them. They can be recruited if they like, respect or fear you enough.

Fight with guns, bow and arrows, or melee weapons

You can target your enemies legs to slow them down, or try to hit their heads for greater damage. You can dodge or block in melee combat - and so can your enemies. Different characters have different skill sets and can level up to improve their Archery, Firearms or Hand to Hand abilities.

Use stealth to hunt zombies, rabbits, or people!

You can sneak up on enemies and assassinate them, or just knock them out cold and steal their stuff. Throw bottles or chunks of meat to distract zombies. Wear camouflaged clothing to boost your Stealth skill. Rabbits and zombies both have a keen sense of smell, so make sure you check the wind direction!

Build a base, plant crops, set traps

As you recruit followers they'll need a place to sleep, a steady food source, and a fire to keep warm. Chop down trees, mine rocks, and look for other resources in the abandoned towns dotted around the map. Set pit traps for zombies and raiders to fall in, or set rabbit traps for food. Assign your community members different roles such as Farmer, Chef, Arrow Crafter, etc. Over time you can build a well-defended, self-sufficient settlement that even produces its own bullets.

Customizable character, Procedurally generated world

When you start a new game you can set up your character's appearance, clothing, equipment, skills, and personality. Or just hit the randomize button until you see something you like. Every game will have a new randomized map with roads, rivers, abandoned towns, and survivor settlements.

Mature Content Description

The developers describe the content like this:

- Contains violence against humans and zombies, and you can hunt animals.
- You can 'skin' corpses and eat the meat or use it as bait, though currently it's not very graphic
- There is a clothing system, which means characters can be undressed down to their underwear.
- Also a fair amount of swearing
