Abadox: The Deadly Inner War
Abadox is a video game for the NES with the subtitle The Deadly Inner War. It is a side-scrolling shoot 'em up in the style of Gradius and R-Type. The game stands out for its unique visual design, since the game takes place in the intestinal tract of a giant alien organism. Abadox is also known for being difficult, since one hit from an enemy projectile is enough to get killed. When a player is killed in Abadox, he must start over at a checkpoint that was passed before the death.
Story
In the year 5012, the planet Abadox is soon devoured by a giant alien organism called Parasitis. After eating the planet, the alien takes the form of the entire planet and tries to devour other planets in the galaxy. The galactic military tries to fight the alien, but to no avail, as Parasitis destroys the entire galactic military except for a hospital ship. It is then discovered that Princess Mary has also been devoured. The galactic military decides to send out its best fighter, "Second Lieutenant Nazal", to try to penetrate Parasitis' body and save Princess Maria before it is too late.
