Gameplay

In Microsurgeon, the player is a surgeon who controls a microscopic robot probe throughout a patient's body attempting to treat various illness and diseases before those ailments terminate the patient. The diseases the patient can suffer from including bacterial infections, brain tumors, cholesterol blockages in arteries, tapeworms, and various diseases of specific organs.

The player gets a quick chance to review the patient's chart before the game begins, giving him/her the opportunity to evaluate where he/she needs to focus attention on the patient the quickest. It's generally most effective to treat the areas that are the most critical initially, and then focus on other areas as the progress or as other conditions are cured.

The robot probe has three different treatment regimens that can be used including ultrasonic rays, antibiotics, and aspirin. The ultrasonic rays treat most conditions found during the game. Antibiotics are used to treat the various bacterial infections that appear in a patient. Aspirin can temporarily disable a virus.

Review

Microsurgeon

Just what the doctor ordered

Microsurgeon, designed by Imagic and produced by Texas Instruments, is arguably the best game cartridge ever distributed by Texas Instruments. It is also one of the newest and among the last to be manufactured by TI. In terms of its quality, I would compare it to the Scott Adams Adventure Series.

Performance: Microsurgeon has been produced for a number of computer and video game machines, ranging from the Apple to Intellivision. The object of the game is straightforward: you play the role of a surgeon whose job it is to save the life of a patient by directing a microscopic probe through his body to the organ or organs that are diseased. You determine the treatment to employ, choosing from ultrasonic rays, antibiotics, and aspirin. Medication is introduced by using the fire button on the joystick or through keyboard input. Having stabilized the patient's condition, you guide the probe out of the body to conclude the operation.

This is a very sophisticated game and describing briefly how it works is difficult. It is impressive in many ways, including its excellent graphics, use of sound effects, and overall design.

The first thing you notice about this game is the graphics. The screen is divided into four separate displays of different shapes and sizes. The largest display is the surgical screen, displaying an inside view of the body of your patient and the location of the probe within it. This display "windows" horizontally and vertically as you make your way through the arteries and veins.

The status screen monitors the patient's vital organs, warning you in advance of developing problems. A small close-up scanner screen shows a magnified view of the location of the probe. A fourth screen represents the patient's room in the Intensive Care Unit. The patient is in a bed, hooked up to an intravenous bottle. Occasionally, he will be visited by a doctor.

Microsurgeon includes several types of sound effects. If you have a speech synthesizer attached, you will occasionally hear the voice of a woman calling for a doctor. Other sounds include representations of an electrocardiogram and heartbeat. These can be turned off if desired.

There are three levels of play: Student, Intern, and Surgeon. You choose the level at the beginning of the game. You also choose which patient to treat at the beginning. There are 1,000 to choose from.

Success in this game is a relative thing in most cases. You can treat your patient enough to stabilize his condition and he will survive, even though the status screen may show that some of his organs are in "fair" or worse condition. Of course, if you do not treat his disease before the status indicator reaches the critical mark, you are in danger of losing him. A very critical condition can go terminal at any time. When two organs become terminal, the patient dies and the game ends.

Your score is measured in the amount of research dollars you are able to accumulate. You start out with a certain sum based on the patient's condition and add to or subtract from it based on your success at treating his condition.

Another complication in doing surgery in Microsurgeon is the need to maintain a power supply for your robot probe. This creates a time limit on your operation. The power supply is drained off according to how fast you are operating and how much medication you use. You can gain power units by hitting viruses with aspirin. The graphics used in this game are like nothing I've seen in any other TI game. Color is used to distinguish the lymphatic system, veins, arteries, and organs. The graphics include a representational display of the upper torso of a human body.

Each medication has its own shape and color, as does each disease. Among the medical problems you will encounter are tar deposits in the lungs, tumors, tapeworms, kidney stones, gallstones, cholesterol buildup, viruses, and infections.

Ease of Use: While the joystick is used to control the robot probe (you may also use the keyboard to do this though it is easier to use the joystick), commands to increase the speed of the probe or turn the EKG monitor or heartbeat sound on or off are entered via the keyboard. Selection of medications is also done through the keyboard. Once you get accustomed to which keys to hit, the game is easy to play. Of course, you must have a steady hand to guide the probe through the patient's veins, arteries, and lymphatic system.

Documentation: The manual that comes with Microsurgeon is comprehensive and extremely well designed. Included is a full-color reproduction of the body as it appears in the game, with coding to allow you to identify the body parts.

Value: I enjoyed playing this game for a number of reasons. It is multidimensional and requires intelligence on the part of the player to succeed. It is also educational insofar as a player must gain an awareness of the body and the location of its organs to do well. Though this is not a game for younger children, those in their early teens who tried it were fascinated by it. Part of this may have been due to the fact that were studying the human body in school.

TI has always had a reputation for producing mediocre game software for its home computer. Finally, the company started coming out with the good stuff, and now it's out of business. Too bad, this is good stuff.

Introduction

Microsurgeon Cartridge

Do you ever dream of being an expert surgeon? Microsurgeon places you in an imaginary operating room where you work against time to save patients in critical need of treatment. In this fantasy setting, you perform experimental surgery to cure a variety of conditions. Each imaginary medical case presents a new challenge to your surgical skills. You gain satisfaction from curing patients and accumulating funds for medical research. Use this manual as your guide to successful microsurgery.

In Microsurgeon, you

• Develop your skills in microsurgery by first performing experimental surgery at the student level on practice patient0
• Treat a variety of different conditions and diseases as you select from 1000 patients
• Use an experimental Robot Probe as your surgical tool
• Diagnose the patient's condition and direct the Probe through the body toward threatening conditions
• Eliminate the conditions with medications from the Probe

With Microsurgeon, you

• Play alone or with a friend
• Use Wired Remote Controllers (joysticks) or keyboard control
• Enjoy multi-screen graphics
• Choose from three levels of difficulty -student,-intern, or surgeon
• Have more fun with synthesized speech that simulates the action and excitement of microsurgery

Note: Microsurgeon is designed to work with or without the Texas Instruments Solid State Speech^TM Synthesizer (sold separately). However, the Speech Synthesizer must be attached to activate the voice of the computer.

Preparing for Microsurgey

You see four small screens during microsurgery. They show the exact position of the Robot Probe in the body, monitor the condition of each organ and the overall status of the patient, and display activity in the patient's room. During microsurgery, the Robot Probe gains and loses power. The amount of power, your accumulated research funds, and the name of the organ in which the Probe is located appear on screen. The number of your patient and level of expertise also appear.

Microsurgeon screenshot with bold red number indicating important screen areas described below

1. Surgical Screen with Robot Probe

Shows the area of the body with the Robot Probe. The Probe is located within a white-bordered square. You see

• Red arteries
• Purple veins
• Orange lymphatic system

2. Patient Number and Level

Show the number of the patient and your selected level of surgical expertise. These appear below the Surgical Screen throughout the game. (The example above shows pateint #90 and surgical expertise as student)

3. Status Screen

Lists each organ and overall status of the patient. The length of the arrows indicates the condition of the individual organs and the patient's overall status.

Arrow Length	Status
No arrow	Good
Between 1st and 3rd dot	Fair
Between 4th and 6th dot	Serious
Between 7th and 10th dot	Critical
Red Arrow	Terminal

If you successfully treat an organ, its arrow grows shorter and eventually disappears, signaling a cure. If you neglect to treat an organ, its arrow grows longer, eventually reaching the right side of the Status Screen.

When an organ becomes terminal, its name is framed in red. In general, when two or more organs become terminal, the overall status line is framed in red. Then, the patient's condition is terminal and the game ends.

4. Patient's Room

Shows a hospital room with the patient lying in bed. A doctor or visitor occasionally appears.

5. Close-Up Scanner

Shows a magnified view of the exact position of the Robot Probe. Use the Scanner to stay within veins, arteries, and lymphatic systems for safe and fast travel. The Scanner does not scan bacteria, viruses, and white blood cells.

6. Robot Probe Location and Power

Shows the name of the organ in which the Robot Probe is located. The organ's name appears when the Probe is centered in the organ. The name of an organ does not appear on the Surgical Screen when the Robot Probe is between organs.

Beneath the name you see the number of power units you have to operate the Robot Probe.

7. Research Funds

Shows the amount of your research funds. The amount is updated periodically.

Getting Started

When the Microsurgeon title screen appears, press any key to begin or press the FIRE button on your Wired Remote Controllers (joysticks). First, select your patient number. Second, select the level of play suited to your surgical expertise. Then, navigate the Probe through the patient's body to areas that need treatment.

Developing Your Skills for Microsurgery

Microsurgery is complex, and your patient's health is in your hands. Follow these steps to develop your skills before advancing to more complicated medical cases.

• Study the manual before you begin.
• Press AID to see a preview of game play functions.
• Select patient number 0, a practice patient, as your first case.
• Select the student level of surgical expertise until your skills improve.
• If you do not yet have the skills to save a rapidly deteriorating organ, treat as many diseases as possible to stabilize the patient's overall condition.

Selecting Your Patient

Patients are numbered O to 999, giving you a variety of surgical challenges.

Type a number to select your patient and press ENTER. To change your selection, press ERASE before pressing ENTER.

Choosing Surgical Expertise Level

Select one of the following:

Press	Level
0	Student
1	Intern
2	Surgeon

Special Keys

Press	Function
4	To hear EKG sound in Intensive Care Unit room.
5	To hear heart sound.
6	To turn off sensors, producing quiet in the operating room.
P	To pause action during surgery. The word PAUSE appears in place of Robot Probe location. Press any key to resume action. Press key 4 or 5 to resume sound.
AID	To see a preview of game play functions

Moving the Robot Probe

You can move the Robot Probe through the body at two speeds. Stay within areas that allow you to travel swiftly and avoid white blood cell attacks. After treating the patient, leave the body carefully through an approved exit. You can play Microsurgeon with one or two players using the joysticks or the keyboard.

Moving through the Body

Control the speed of the Probe by pressing the 7 key (Slow) or 8 key (Fast). Your quickest route is through the arteries, veins, and lymphatic system. Stay within these routes to avoid constant attack by white blood cells (phagocytes).

Stationary white blood cells (lymphocytes), located in the arteries, veins, and lymphatic system, cannot be destroyed. When moving through lymphocytes, the Robot Probe slows down and can be attacked by phagocytes.

To move from one part of the body to another, move the Probe in the desired direction. The Surgical Screen automatically shows the new section of the body as you proceed.

To leave the body, pilot the Robot Probe slowly through an approved exit to prevent damaging your Probe.

Identifying the Wired Remote Controllers

Each Wired Remote Controller Joystick) serves a different function in Microsurgeon. The primary joystick controls movement and issues medication. The secondary joystick only issues medication. Be sure to identify and use the primary joystick for one-player games.

In two-player games, the player moving the Robot Probe uses the left side of the keyboard or primary joystick. The player issuing medication uses the right side of the keyboard or the secondary joystick.

Using the Wired Remote Controllers for Movement

To pilot the Probe, move the lever of the primary joystick in the desired direction.

Lever Position	Directions
Forward (toward the FIRE button)	Up
Backward (away from the FIRE button)	Down
Left	Left
Right	Right
Diagonal	Diagonal

Note: The ALPHA LOCK must be in the OFF (up) position when using the Wired Remote Controllers (joystick).

Using the Keyboard for Movement

Movement of the Robot Probe is controlled by the following keys:

Key	Directions
(↑) E	Up
(↓) X	Down
(←) S	Left
(→) D	Right
( ) W	Diagonally left, up
( ) Z	Diagonally left, down
( ) R	Diagonally right, up
( ) C	Diagonally right, down

Treatments

There are three medications for the eight conditions that can attack the body. Each condition is treated by one medication. Three medications are contained in the Probe. You must select the right medication to treat each condition. Once a medication has been selected, you can use it repeatedly until you select another medication. Because the Surgical Screen shows only a small portion of the body, a map is provided to assist you in maneuvering during surgery.

Selecting Medications

To select medications, use these keys.

Press	Medication
1	Ultrasonic Rays
2	Antibiotics
3	Aspirin

Select the appropriate medications to treat each condition.

	Ultrasonic Ray
	cholesterol buildup (gray, in arteries)
	gallstones (dark green, in gall bladder)
	kidney stones (light green, in kidneys)
	tapeworms (red, in intestine)
	tar deposits (black, in both lungs)
	tumor (gray, in brain)

Note: Ultrasonic Rays also destroy attacking white blood cells (phagocytes).

	Antibiotics
	infection from bacteria (green, appears throughout body)
	Aspirin
	viruses (red, appear and disappear throughout body)

Note: Aspirin slows down viruses, but does not destroy them.

Playing the Game

You help your patient by issuing medication to destroy dangerous conditions. Use the convenient joysticks or keyboard to maneuver your Robot Probe carefully into position. Select the correct medication. Fire medication at the condition. Some conditions require repeated medications for a cure. If you perform surgery with a friend, you have a better chance of curing difficult cases. Try to save your patient and exit the body before the Robot Probe runs out of power. When the game ends, you can play again at the same level of expertise and with the same patient, or you can choose a new challenge.

Using the Wired Remote Controllers for Issuing Medication

To release medications from the Robot Probe using the primary joystick:

• Hold the FIRE button down, move the lever in the direction you wish to fire, and release the FIRE button.
• Press the FIRE button again to issue medication in the same direction.

To release medications from the Robot Probe using the secondary joystick:

• Move the lever in the desired direction. (It is not necessary to press the FIRE button.)

Using the Keyboard for Issuing Medication

To release medications from the Robot Probe, use these keys:

Key	Directions
(↑) E	Up
(↓) X	Down
(←) S	Left
(→) D	Right
( ) W	Diagonally left, up
( ) Z	Diagonally left, down
( ) R	Diagonally right, up
( ) C	Diagonally right, down

Ending the Game

The game ends when one of the following happens:

• Patient's general status becomes terminal
• Robot Probe exhausts power supply while still in patient
• Robot Probe exits the body properly through the ear, eye, nose, or mouth
• Robot Probe exits the body improper through any other point

Playing Again

• Press REDO to play using the same options.
• Press BACK to select new options before starting a new game.

Earning Power Units and Research Funds

As a microsurgeon, your primary goal is to save your patient. For your services, you are awarded funds to promote medical research. The total amount of research funds and power units appears on the screen. Research funds are recalculated periodically. Your level of expertise and your patient's initial and final conditions influence the number of power units and research dollars you accumulate.

Surgical Tips

As you play Microsurgeon, you discover strategies to help you become a stronger player. As you become more experienced, you may wish to play at more advanced levels that challenge your new skills. Watch your playing ability improve with each successful game.

The Skilled Surgeon

1. A skilled microsurgeon

• Treats the most dangerous conditions first
• Avoids phagocyte attacks by staying within red, purple, or orange areas
• Uses the Close-up Scanner to navigate the avenues of the body safely
• Watches the status lines to detect changing conditions of individual organs and of the patient

2. Some conditions on the Status Screen require special diagnosis and treatment. A skilled microsurgeon

• Cures infection by destroying bacteria
• Treats heart trouble by eliminating cholesterol buildup in arteries throughout the body
• Destroys cholesterol buildup and tumors in the brain
• Improves the status of the lungs by treating both of them

Challenges of the Game

Watch out for these special challenges for microsurgeons.

• The Robot Probe and Scanner are experimental surgical tools and are slow to find and display diseases. When the Status Screen indicates disease in an organ, wait in the organ until the disease appears, and then destroy it with proper treatment.
• Lymphocytes impede the movement of the Probe and allow phagocytes to attack.
• Lymphocytes increase as the patient's condition becomes more serious.
• The Robot Probe cannot destroy lymphocytes.
• Viruses are disabled, not destroyed, by aspirin.
• Tumors reappear more quickly than other conditions.
• Phagocytes violently attack the Probe if you stay outside the safe travel routes for too long.
