Drive a single tank against the enemy army. Defend your teleporter and prevent enemy units from escaping through it. Do not leave the battlefield or you will be terminated.
Shoot the incoming enemies to protect your base. Collect weapons and turrets that automatically fire on the incoming missiles. Push the turrets around the battlefield to take advantage of their range and abilities.
The Federation is under attack and doesn't seem to be holding its ground very well. It is up to you and your Mechwarrior to put an end to their advancing armies.
