C: The Contra Adventure1998

The player takes on the role of Golgo 13 (also known as Duke Togo), an assassin whose objective is to destroy the leader of the Drek group. On the way, Golgo 13 must pass through several areas, including East Berlin, Athens, and Alexander Island, which is located off the coast of Antarctica. It is necessary to navigate several mazes in order to win, but one maze is a fake base with no way out. The mazes account for a large amount of the frustration players encounter with this game. The instruction manual contains maps for the mazes.

This game is action from beginning to end, do not think that you will have a moment of peace, even because Aliens are at war with planet earth, and resting will be your least concern.

It's a nightmare, but it's true! Research shows that we are the actual aliens on Earth, and the ruthless Xevions are the original inhabitants. Now the Xevions want Earth back -- minus humans! Their invasion forces are fierce -- the land is crawling with deadly Domogram Rovers; the sky is black with Toroid Patrol Fleets and Zoshi Death Squads. Our puny weapons offer no defense. Earth's only hope is our powerful new Solvalou Fighter Plane. Its pilot will have a single mission: Penetrate the enemy ranks and destroy the Xevious Mother Ship. The mission is dangerous. We can't guarantee success. But at this point, it's do or die! One small problem. We still need a pilot. Any volunteers?
