My Pico-8 game inspired by the 1980 Stern Electronics game and made possible by the excellent  "Speako8 Speech Synthesis Library" by @bikibird -

How to Play

Shoot the robots. Avoid the walls. Don't stay in a room for too long!


[X] - Laser (stands still so you can accurate fire in one of 8 directions)
[O] - Laser (while running)

Thanks To

Great conversion! I think you forgot to put the funny phrase “Chicken, fight like a robot!”, when you exit a screen without killing any opponent.

thank you!

I had to be really picky about the speech phrases I used. Could get that one to sound intelligible unfortunately. 

Great little game.

I pumped some serious coin into this thing back in the day...

I would like to be able to shoot when standing still.

You can. Hold X and then press a direction. Z (or [O] in pico-8) lets you run and fire at the same time.

Thanks I didn't catch that. :)

so cool...but how do you do the digital voice????

I used a library called speako8. See the link in the description above. It’s awesome!

sorry i don't pay attention to the description...thanks
