You have just been informed of a mission dubbed "LaCucaracha" that you are to fly solo. The enemy is about to launch dozens of electromagnetic weapons at military complexes you must protect. These weapons are cruise missiles which are called "cockroaches" because they fly only a few hundred feet off the ground and almost seem to evade pursuit. You will be trying to stop them with missiles of your own, (9x heat seekers) specially designed to seek and destroy them. You must peruse and stop all the missiles before they reach their destination. If just one gets through, mission failed.
When flying this mission, it almost seems like something out of Star Wars. Just spawn in, wait for clearance and go. You're fueled and armed. Multiple difficulty levels.
