Leave this door behind you close

Recommended loadouts:
Wave gun/zap gun
Crystallized harpoon gun
third weapon can be anything (Apparently you can get another harpoon gun if you have crystallized harpoon gun)
Gerch device (To help you for hacking drops)
God mask (Helps with rebuilding barriers as zombies will keep hitting you and allows you to breathe underwater, Just finish all your challenges)


Recommended perks:
Jugg (Obv unless you're doing no jugg challenge)
Speed cola (Really helps for wave/zap guns and harpoon gun)
Bandolier perk (For more ammo in reserves)
quick revive/mule kick (Get mule kick if you're confident on getting quick revive from crawlers)

P.S try to get all perks from crawler rounds (You can melee if strong enough or use the harpoon gun but make sure you don't miss)


To do this strat:
Shoot your crystallized harpoon gun in these two white spots. It will create like an electric trap that kills all the zombies from that doorway. Use your zap guns to kill the zombies from the window to your left. If there's too many zombies from window, use the wave gun. Most of the zombies should come from two spawns in pm63 room and some from the window.

Keep in mind:
- You have to be rebuilding barriers all the time while shooting zombies in the window
- Be on the lookout for your electric trap from your crystallized harpoon gun. When it breaks, make another one.
- For using specialist. I like to shoot one into the window and one towards the door in front of you.
- The tether from your crystallized harpoon gun is limited, make sure you're not too far from the white spots you're shooting at


For the crawler round, stand near the door you leave closed and use your crystallized gun to camp.


Set up progress:
1. Speedrun through five rounds to get the wrench. I like to stay in pm63 room although you can also stay in the camp spot. It should be in the camp spot across the zombies window.

2. Camp in the camp spot until round 9 or 10.

3. Open the other door from spawn. Instead of opening through cafeteria, take the doorway on the left to go under. (You want to keep two doors close in cafeteria if you want to go beyond 200+)

4. Interact with the metal door that the doctor is trapped in. Should turn on the computers in submarine launch facility.

5. Open doors to get to power. You should have enough.

6. Do the computer step and simon says to get the code which can be inputted in the submarine where pack-a-punch is. Get the valve. I recommend you build the shield first for the simon says since you'll be holding a zombie.

7. Do the valve steps to free the doctor. Escort him throughout the map until he gets to the crystal part and grab the crystal.

8. Now you just get the perks you need, both specialist and shield, and the loadouts you need from the box (Use the hacker if you haven't gotten it already). Make sure you do all the challenges for the god mask (You can change specific challenges that you find hard to do by hacking them)

Once you have everything you need, you can start camping.

For going 200+, the cafeteria is the best spot. Leave two doors behind the steam trap close. Make sure you install the valve for the steam trap.
