Mission Asteroid

Mission Asteroid (shown as Mission: Asteroid in the manual and on the title screen) is a graphic adventure game for the Apple II written by Ken and Roberta Williams and released in 1980 by On-Line Systems.

Publication history
The game was released as Hi-Res Adventures #0, despite being released after Mystery House and Wizard and the Princess. It was meant as an introduction to the adventure game genre so it was made easier than the rest of Hi-Res Adventures games.

It was ported to the Atari 8-bit computers and Commodore 64.

Reception
Mark Marlow reviewed Mission: Asteroid, Mystery House, and The Wizard and the Princess for Computer Gaming World, and stated that "Mission: Asteroid is the simplest of the group and only requires a few hours to solve".
