Survivalist Invisible Strain — is an open source community building game after the breakdown of civilization. You can recruit survivors by making them like you, or make you respect you, or fear you. You will need to keep them warm, feed them and build a settlement to protect them from zombies, looters and everything else. Use tricks, weapons or words to achieve your goals. The game uses a randomly generated world with a story mode. 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 gossip, food, sleep, warming, work and struggle. Some will give you quests; it is up to you how or whether to complete them. They can be hired if they love, respect, or fear you enough.
