== How to run and requirements ==

The game can be started from FLOP reader, DOS or QMEG menu. Basic have to be switched off!

This is a game for two players controlled by two joysticks.

Exit the title screen by pressing the START key.

After the next loading from the disc, the game screen will appear. However, the game still needs to be started by pressing the START key again.

== Game flow ==

In the center of the screen, the attacking aliens are lined up in 4 rows of 10 creatures each. A spaceship flies over them.

At the bottom of the screen are moving cannons controlled by the player. The cannons can move sideways across the width of the playing field.

The game basically looks and acts like the familiar Space Invaders. But apart from two players at the same time, it has a few significant differences:

• Aliens don't shoot.
• The aliens always come down one micro row (i.e., the height of one pixel), not the height of an entire row.
• Aliens move down when a line labeled "Critical Horizon" (which moves with them) hits the edge of the image. Thus, descent is not slowed by eliminating the aliens' edge columns.
• Players do not lose at the moment the first alien touches the ground, but only when the line labeled "Critical Horizon" hits the ground.

The game has 6 difficulty levels. The level ends when all aliens are shot. Their ship is ignored.

The next level is started by pressing the START key. In each subsequent level, the enemies move faster and start lower above the surface. In higher levels, the aliens start just above the ground. In the last two, even one or two rows of enemies are missing.

The bottom panel shows the points earned - the first player's points on the left, the second player's on the right.

For shooting down an alien, the player gets 1 point. For shooting down a ship (only one in each level) the player gets 10 points.

== End of game ==

The game ends after successfully completing level 6 or losing, i.e. all surviving aliens have reached the ground, or the "Critical Horizon" line has reached the ground.

From the game over screen we learn the names of the creators and also that the author created the game for his son Tobík.
