Call of Duty: Black Ops 2 - Revolution DLC - Vertigoner Achievement / Trophy Guide

Описание: You firstly have to build the Trample Steam which you need:

The flag pole
The brown air thing
Small steam engine
Metal square
These can either be found in the starting area or in the room next to the starting area (You pay 750 points to open the door). Before you can build it though you need to turn on the power which can be accessed a variety of ways but the best way is to go down the lift at the start, jump to the next building and open the door in front of you to get to the power switch. Once you've done that use the elevators to get to the roof, then jump back to the building you started on. Now, all you need to do is pick each part up then go down to floors on either of the two elevators here to reach the workbench (This is much easier with 4 people).

Once you've built it just set it up with the up button on the analog stick and wait for it to pull back, zombies will be attested to it so make sure they don't break it. Once it has been pulled all the way back simply watch the zombies in front of it get flung into the air. Repeat 10 times in one game.
