This one can be used to get the achievement on Valfross lvl 40, where you are required to destroy the wall without explosives.
Just drive the tank (keys: [Up] [Down]) in the wall and turn it around or spin it (keys: [Left] [Right]) to destroy the remainders of the wall.

Use the scoops to push away the debris otherwise you might get stuck. Try to avoid getting things on the underside of tje tank.

Avoid driving and turning at the same time. The tank can do/handle this, but while testing this, some of the wheels eventually broke when continously ramming the wall, so keep that in mind.
