Alien Syndrome


What's Happening

The Year: 2089. A mysterious alien space fleet invades human occupied space. Called the Alien Syndrome, they are unlike anything mankind has ever encountered. Their ships are as large as cities. They have weapons powerful enough to destroy planets. With the entire human race threatened, the Alien Syndrome must be stopped.

A battalion of Earth Command Troopers attacks the alien fleet. But they are captured and held hostage. In desperation, Earth Command asks for volunteers to go on a rescue mission.

Only two soldiers are brave enough to step forward. They are Earth Command Troopers RICKY and MARY, the meanest combat troopers in the galaxy!

Armed with only a short range combat rifle, they must infiltrate all seven alien ships, rescue the hostages and escape...alive!

The odds are against them. The aliens can appear anytime... anywhere. The hostages are depending on RICKY and MARY...and on you!

Know Your Friends

The hostages. They are humans wearing green coveralls. Rescue them by placing your player on top of them. When you have rescued all hostages aboard the ship, an exit door will open, allowing you to fight the Alien Boss.

Know Your Enemies

Aliens:

There are two kinds of aliens in each round, each kind a different color. If they touch your player, you lose a life. They can also shoot at your player. If you are hit, you also lose a life.

Aliens can appear anytime...anywhere...by flickering into existence. They cannot harm you when they are flickering and you can't shoot them! You are safe even if they appear under your player. But as soon as they become solid they are deadly. If an alien appears under your player, move and get ready to shoot!

Defenders:

You'll find them in every room...on every ship. They look like round, green, sleeping faces. But get close enough and they shoot to kill! And if you touch one...you lose a life.

Luckily, they can't move. You can knock them out temporarily with a well placed shot. When hit, Defenders turn gray and become harmless. But after a short while they become active again. Be extra alert when battling groups of aliens. The Defenders can turn the fight against you!

Alien Bosses:

These large and dangerous enemies are the most powerful aliens you will find on each ship. They guard the exit stations. You can't proceed to the next ship unless you defeat the Alien Boss.

Every Alien Boss has a weak spot. They only way to defeat an Alien Boss is to discover it and shoot him there. You will know when you find it. Each time an Alien Boss is hit in a weak spot, his body flashes.

Upgrading Your Weapons

When the aliens captured the Earth Command Troopers, they placed the trooper's weapons in different places throughout the ships. You will find them in the walls. If RICKY or MARY touches the weapon, they have use of it until they get a new weapon or are killed.

FireBall icon

FireBall: A flame thrower that shoots large bursts of fire! Makes it easier to hit the enemy.

Laser icon

Laser: Laser rifle is powerful enough to blast through groups of aliens with one shot!

Smart bomb

Smart Bomb: Touch this symbol and every alien on the screen will be destroyed.

Warp

Warp: Getting this symbol will instantly "warp" you to another part of the alien ship you are in.

Mystery

Mystery: Depending on where you are in the ship, this symbol will make you temporarily invincible...or nothing will happen.

If you happen to get N, your present weapon reverts back to the one that you had originally.
