Yes you can do three people or four. But first you have to get inside one another. This has been posted before but in that video they showed no tutorial.

Here is a how to do tutorial:

1. First get enough money to open the left side (Facing the clock) until the bridge.

2. Get a crawler. Or a slow zombie.

3. Turn the power on and go back on the bridge.

4. Now once you get to the teleporter across the bridge tell one person to lay down in prone.

5. Then tell the other guy to jump on the guy laying down and the guy laying down to stand while he does it.

6. Tell the two people that are in each other to prone.

7. The the third person to jump and repeat step 5.

8. once you are in there tell everyone to crouch and stay still. Once the crawler comes to you kill it and there you go.

Note: This was posted by SewerWaste and Wolfdemon19. I will not give credit for them finding it but they did post it. SewerWaste told me he did not find it. So if you say i copy your post and you are not SewerWaste or WolfDemon19. I will just ignore you because you copied the post.

(By the way this is how to do the three person insta round glitch. Not just one.)

This is also on Der Riese. I do not have a cap card but if you do then give me your GT so i can show you and you record it.

I will not give credit to anyone who posts it below. I don't know the person who found it but i don't want to give wrong credit. But SewerWaste and Wolfdemon19 did post this (But not the 3 person one.) first. Well at the same time.

Wolfdemon had two ways SewerWaste did one way. So that is why i give them both credit.

Also give SewerWaste and WolfDemon19 rep. And me. I got bad rep as a joke and i can't get it back.
