Werewolf chase for zx80

I redid the entire game. After you reach the end, you realize that the world is about to end. Yes gentlemen, zombies. Due to the sheer amount of text and some graphics, you need 32k. Enjoy. It's not so much a game, more of an attempted adventure. Too bad, the zx81 can't do color.

Obviously sinclair basic lacks this (unti...

Attrition for ZX80

I did my best to cram this into 1k. The USA is being invaded by aliens from another world. You are charged with defending either Santa monica, Santa clara or Chicago, depending on where you place your men. The variable a$ is the only one used. It serves two purposes: 1. to show which city you are de...
