Space Launcher

Space Launcher is a arcade game first released by Nintendo in 1979. While it's hardly remembered today, it was one of Nintendo's first original titles. Previously, many of their games were clones of games such as Space Invaders and Breakout, but Space Launcher was a unique concept, and would even go on to be imitated in Frogger.

Gameplay
In Space Launcher the player must guide a missile from the bottom of the screen, to one of the four ports on the other side. In the space traversed the player must avoid two sets of dangers, a number of sparks in the beginning, and two rows of enemy ships when closing in on other side.

The missile moves slowly on its own, but the player can speed up the flight by holding down the action button. The ship can be moved from side to side to avoid the sparks as well as the projectiles from the enemy ships. When the missile reaches the enemies, a shield is activated in front of it. This allows the player to destroy the enemies by ramming them with the shield. The missile can then safely land in one of the ports.

The flight back plays out the same, starting with an activated shield, but there are no specific landing points this time. As the player successfully returns to the start, the difficulty is raised. More sparks are added, and the enemy ships fire more projectiles.

The game supports alternative play for two players.



Scoring
Points are received for the following:


 * Destroying an enemy ship with the shield activated: Randomly chosen between two numbers, see table below
 * Successfully landing in one of the ports: Number shown above port, see table below
 * Returning to the start untouched: 500 points

An extra life is also received after reaching 1000 points.

As the player completes the mission over and over, the points received increases. The table below details how points are calculated.

Legacy
Space Launcher was apparently rather well received at its time, as Far East Video proceeded to distribute the game in Europe. Despite this, it seems to be forgotten today. While many of their early games have been referred to in various newer Nintendo games, Space Launcher is not one of them.

Frogger, which was released in 1981 by Sega, is based on a similar gameplay idea. A frog has to be navigated from one side of the screen to the other, while avoiding obstacles. While the two games are different enough to have been created separately from each other, it's possible that inspiration was taken from Space Launcher.
