We all know the main ones, a madman in a mask stalks a bunch of young people and usually eliminates them one by one. The motives of the villain are usually a mix of avenging a wrong done to them, or something is wrong with them mentally that facilitates their need for killing these people.
Survival horror is a little bit different, but could still be considered under the “slasher” subgenre. The main point of survival horror is tension and surviving an environment. The main character is often put to the test to survive against all odds. The adversity could come from one single person, a group of people, or an evil company set to eliminate people who would expose them.

Book: "The Final Girls Support Group" by Grady Hendrix

Lynnette Tarkington is a real-life final girl who survived a massacre twenty-two years ago, and it has defined every day of her life since. And she’s not alone. For more than a decade she’s been meeting with five other actual final girls and their therapist in a support group for those who survived the unthinkable, putting their lives back together, piece by piece. That is until one of the women misses a meeting and Lynnette’s worst fears are realized — someone knows about the group and is determined to take their lives apart again. But the thing about these final girls is that they have each other now, and no matter how bad the odds, how dark the night, how sharp the knife . . . they will never, ever give up.
