Minefield was published for the TRS-80 in 1982 by Molymerx.

Minefield games for micro-computers are quite common but this is one of the best we have seen. The idea of the game is to successfully cross a minefield in which a number of hidden mines have been laid. If you step on one you will be blown up. In order to help you across, you are equipped with a mine detector. Unfortunately, this can only tell you that mines are in your vicinity, not their exact location, furthermore, it only has limited battery life. You will probably have to go about a quarter of the way on your own. The field in which the minefield is situated, is also strewn with rocks. These are a mixed blessing, for although there will not be a mine under them, they are too big for you to climb over! You may have to get yourself into a position where you are surrounded by rocks and mines! The rocks of course are visible. Your path through the minefield is plotted, this enables you to retrace your steps - however it doesn't get you too far as you are supposed to be going forward! After the game is over you may view the placement of the mines - even if you have been blown up! Movement is effected with the four cursor arrow controls and automatically repeat if you hold them down, this lends itself to an easily played, and therefore enjoyable game. The total number of steps in the field are 180 and as there are 20 mines and 20 rocks, the odds are set rather nicely! If you step on a mine and then choose to display them all, the one upon which you trod flashes on and off to separate it from the others. A nice touch which is the hallmark of a good program.

The game requires 16K and works on the TRS-80 (Model 1 & 3) and System 80 (Mark I & II).

It is unclear who wrote the game, since Molymerx distributed "the best programs available on the North American and European markets".
