How to earn the 100% in Friday the 13th: The Game legitimately

This method still requires SAM (Steam Achievement Manager) but we won't just be giving ourselves the 100% for free. I have created a list of every achievement and a progress bar for each one, I also grouped them up by whether you need SAM for them or not.

You'll need at least 1 partner to help you with these achievements in game. Also meaning that you'll need the online patch. (Roll Credits is the only achievement that requires 4 people. And One For Good Measure is the only achievement to require 7 people.)

Use this link to download the online patch → https://archive.org/details/f13-onlinefix
Make sure you download the patch as a RAR!

You'll then want to unzip the folder and copy the files over the game's current files!

You can copy and paste this below into steam notepad or a document to keep track of achievement numbers. ↓

Every time you are to complete an achievement, you'll need to go into SAM and unlock it after you have finished tracking it like normal. So you're basically just unlocking achievements you've technically completed, but the game no longer tracks.

Using the strike-through tool is very satisfying when completing achievements!

You'll at least need one other person to trigger it.

Step 1: Repair the car as a counselor.
Step 2: Allow Jason to hit you with a throwing knife as soon as you start the bed hiding animation.
Step 3: Get into the car and let Jason destroy the bed. (This will put your counselor into a bugged state, but you're not yet immortal)
Step 4: Setup a bear trap outside of the car as Jason`
Step 5: Jason will need to grab that counselor out of the car. (If you've done it right up to this point the counselor should now be laying on the floor forever.)

If you've done the steps above correctly, the effected counselor will now be invulnerable to all damage. Whether that be physical, or magical.
You can easily farm kills, or do whatever environmental kills you may need.

Below are some visuals on how to do this from both Counselor and Jason!
