This is a basic guide on how to get back to Level 0 after beating Level 1. Whether that be for the challenge or if you want back for whatever reason,
How to get set up
So firstly, you will need some crowbars.
I highly recommend you bring some friends with you, as you have to carry these items through multiple levels without dying.
I recommend you scavenge Level 4 for almond water and other food items.
You will have to be at Level 4 anyway, so there is no reason not to do this.
Now, Just run through the camera section; don’t worry about being spotted; it doesn’t matter at all.
Once in the security office, grab a few crowbars. If you have one other person, each person grabs two.
Run back to The Hub; you are ready to start the “challenge”.
The next few levels
So now you will play through Thalassophobia as you normally would. Make sure to play it safe and not do anything stupid.
You really don’t want to die with the crowbars, as you can’t get any more from this point onward.
The cave system will be difficult, but the more people you have, the easier it will be. Just play it safe.
I advise you to use Juice to run past the Moths and Skin thieves.
One player can be a sacrifice so the others can move on. Just make sure you take their crowbar before you send them to their doom.
Now you will be in the Level 0 sublevel.
This is pretty easy; just run to the locker you find the chainsaw in, and in the corner is a vent.
Use the crowbar to open it up and walk through.
You are now back at level 0, Ready to play the entire game again!
