Space Chaser (c) 1979 Taito.

Space Chaser is a 2-Dimensional maze racing game. You control your rocket through the maze to pick up the dots while at the same time avoiding the rocket, or rockets, that are constantly trying to ram you. Successfully get through one maze and many more await you. This is good practice for freeway driving in the big city.


Board Number : RTNxxxx

Prom Stickers : RT13-22

Main CPU : 8080

Sound Chips : SN76477, Discrete circuitry

Players : 2

Control : 4-way joystick

Buttons : 1


Released in October 1979.

Also released as a Cocktail model : "T.T Space Chaser".

This is probably the most manic of the "Head-on" type of games, as instead of a car (or 2) you're trying to avoid a head-on collision with, you have a missile trying to ram into you. This gives added pressure, since you must be able to outrace the missile at the end of the round.

Maybe also known as "Missile Chaser".


Dots : 10 points X level number.

Levels start at 1 and go up to 9. After that level 9 keeps repeating itself.


* How to finish off the first screen :

1) Let your rocket finish off the half of the bottom row you are on, but turn around before you turn the corner. Turn towards the center when you get back to where you were.

2) Finish off the ten sets of two dots in the middle. Watch out for the missile trying to strike you. Although you should have no problem with giving your rocket a moment's needed boost, try to do as much as possible without boosting through the center. You'll need it later.

3) Take the circle of dots that surrounds the inner area.

4) Go to the bottom row. You should have the left half of the bottom line ready. Go around, finishing the dots.

5) On the last row, hit the boost. You'll need it to finish.
