This is the third of Sierra On-Line's Hi-Res adventure games and continues in the high-quality tradition of Wizard and the Princess. In it, your mission is to destroy an approaching asteroid before it collides with the planet Earth.

The elements of the puzzles are individually easy to solve. In fact, Mission: Asteroid is a very easy adventure game, at least right up to almost the very end. The designers let you get tantalizingly close to winning. Emerging victorious is another matter, however. It's a real bear to fit all the necessary elements together within the fixed number of allotted moves. The time limit, at five minutes per move, is of the essence. You're allowed a margin of error of only two moves. When you think you've solved the puzzles, you need to start at the beginning. Saving a game requires an additional move. Also needed is a complete map and, preferably, a written sequence of moves you plan, as things can be easily overlooked with catastrophic results.

All in all, it's a well-done winner, totally straightforward and solvable, even though there may be times when you'll be convinced that you can't "get to there from here".
