Infiltrate into the enemy zone, shoot down all the baddies and rescue the hostages in this on-rails shooter.

Use your mouse.

If you lose all five lives you can use a credit to continue playing. If you have no more credits, it is Game Over. Note that there is a short rest period after a continue. To defeat the Bosses, you must shoot at their weak point. Bosses have more health and deal more damage on harder skill levels (and are much more difficult to beat).
