Space Ambush is a clone of the arcade hit Galaxian. Continuing from where Space Invaders left off, you are trying to destroy a fleet of invaders, except that now they can break formation and dive bomb you. This version is a little unique in that you can play with either the keyboard or the joystick.
Strangely enough, I have seen two versions of this game: the official Computerware version (as shown in the intro screenshot above), and one labelled as "Promotional Copy" from "Brand X Software". The "Brand X" version is identical except the sound routines are TOTALLY different. I presume that Andy shopped the game around, and when Computerware decided to sell it, they suggested changing the sound effects to eliminate the constant "white noise" background sound that the original version had.
