Recently, Global Cortex has been the target of repeated attacks perpetrated by an unknown organization.

Their activities tapered off after several back-to-back failures, but have resumed again in earnest since acquiring a new source of financial support.

According to sources we will no disclose, they intend to infiltrate a stealth bomber into Adan City and disrupt scheduled test exercises.

If the attack succeeds, our reputation is ruined. Destroy the bomber before it reaches the testing grounds.

This mission requires you to have a decent booster and firepower for taking out the bomber. Missiles or a left arm howtizer would easily do the job. When the mission begins, simply destroy the enemy forces that occupy the city. Eventually, the bomber will begin its approach and a timer will appear onscreen. This won't be how long you have to destroy the bomber but how long until it will spawn. Once it does, simply boost up to it and lay into it as much as possible until it falls. Once it does, the mission is a success.


  • Regina's Raven test takes place off-screen in this mission.
  • Enemies will continue to spawn until the mission ends.
  • If you have a good enough booster and generator, you can fly up and land on top of the bomber itself. You'll have to run constantly to keep from falling off, however.
