Space Invaders!

A pretty faithful IF-remake of Space Invaders: The aliens drop their intergalactic missiles at you; you fire at them with your gun. As a game in it’s own right, I suppose it would be quite a disaster. But, of course, now, it’s not a game in it’s own right: it’s a rendition in text of an old graphics video game. That makes it kind of corny fun—to players who are familiar with the original game, that is.

I don’t think there’s a way actually to win this one (which is quite fair, since there never was a way to win Space Invaders in the first place, was there?), but I didn’t have the superhuman patience nor the subhuman pigheadedness to keep playing long enough to be sure of this.
Also, at a certain point, the author introduces an original element to the game …

This TADS game is part of the IF arcade pack, and is probably the most creative of the 3 reworkings of space-invader type games.

You are in a line of bunkers, and you can dodge left and right, in and out of them as you shoot the invaders.

There are intriguing hints of a storyline, but they seem to go nowhere.
