He's instructed you to destroy a powerful drug cartel, free innocent hostages and take down the murderous Drug Lord. No sweat, right? As you slip into the drug cartel's bases, you find yourself hopelessly outnumbered. Your only chance is to get better firearms and ammo, and find your fellow agent with the bombs.
