Play 2 players versus on the last level of Deathtoll.

When the boat comes, as a survivor head at the back of the boat and the survivors automatically go to the boat.

As the infected you will become tank, just go on beside the bridge in front of the boat then wait for your control meter to run out!

Simply, you become one of the infected and then you move to the boat as well.

Do this when you can't be tank anymore. Your teamates will not be alive but you are and you can't be hit.
