John, you're back into action! A druglord from New York has taken control of important mexican top-secret documents and he's blackmailing the mexican government in exchange of military weapons. Eliminate all resistance and get those documents back!
You and a handful of others form the Last Line of Defense, pooling your remaining stockpile of weapons, special ammo, bunker defenses, and super-weapons to fend off the onslaught by virus infected, bloodthirsty Ravagers.
Strategically control the battlefield and hold the line against enemy tanks by deploying your own fleet of battle tanks to counter them. It's also possible to take a full control of your tank. Good luck!
