X-COM BASE-01 Assault

Recently, I got my hands in the code for a text adventure that claimed to be the "AFTERMATH OF THE ASIMOVIAN DISASTER". But, after adapting it to run in the CoCo, I realized that besides a few words dropped here and there, it had nothing to do with any of Asimov's novels.
I was a bit disappointed, until I realized that the game engine had potential. It is quite simple. Rooms are stored in an array R(X,Y), where X is the room number. The first 6 values of Y have the room number to which you will move if going in that direction. (4 cardinal points, up and down). The 7th and 8th values have a number indicating which enemy - if any - is in that room, and what item is there.
It was then that I decided to write my own adventure, inspired in the assault to an alien base in the original 1993 X-COM game.
Your goal in "X-COM BASE-01 Assault" - I needed a name that would fit nicely in the intro screen - is to find a Hight Explosive charge, set it in the base's control center, and leave. Oh, and not getting killed by the aliens that are still around.
To move around, use the arrow keys, (or n e s w), u and d to go Up and Down, r to run, f to fight, t to throw a grenade, and m to use the Medikit

The game ended up being quite large, at almost 19 KB, although I will confess that this time I did not optimize it for size or speed, as the speed was more than enough, and saving 1 or 2 KB would not make a real difference.
So here is a disk image with a version in English and another in Spanish, plus the original "Asimov" adventure game.
Right below, you will find some technical information about the game, but be aware that it may contain spoilers! ;-)
