|Objective||Destroy 90% of the cannons|
The player is required to destroy the shrapnel cannon.
In order to do that, the machine is required to be shelled with armor in all side or capable of moving quickly to minimize the damage. An alternative is to simply build a small, fast vehicle that has enough power to smash the cannons.
One notable thing is that the cannons don't keep shooting forever. Each cannon shoots only a few times and then stops alltogether, and they run out quickly as well. This makes it possible to wait before you start moving IF you have a machine that won't take damage from all those cannons.
