A missile command minification in 1024 compressed bytes.

The earth is being invaded by aliens, they are bombarding all major cities with missiles. You are in control of air defenses in your city. Fire anti-missile ballistics into the air to create fireballs and destroy the incoming ordinance. Be careful not to aim on the ground near your city, the fireballs can damage your own buildings.

Your city has four anti-missile batteries, each can fire one anti-missile ballistic at a time. If all your batteries are destroyed, all hope for your city is lost, and perhaps the world may fall to our new alien overlords.


  • arrow keys to target, X to fire.
  • left shift toggles using the mouse to play.
  • control+M mutes sounds.

Please reset the cart if you wish to play again.

You score a point for each battery in operation per missile you destroy. So the longer you keep all batteries safe the more points you get. The aliens increase their attack over time, an average game lasts around 5 minutes.

Feel free to share your scores in the comments! Now go forth and defend earth.

Known Issues

The arrow key movement does not restrict you to the play field, you can target outside the visible areas, try not to lose your reticule :) Sorry about this, I ran out of tokens for bounds checking.

This cart is an interactive rail demo, press any of the Pico keys (Z, X, or Arrow keys) to advance to the next step:

  • Roll the Dice, in two steps: picks two random numbers A and B
  • Computation: Runs the simulation until it reaches the answers
  • Outcome: Displays the sum of A and B

Wireworld is a Turing-complete cellular automaton (CA) suited to simulating electrons moving on copper wire. This cart implements a Binary Adder: Two numbers represented in binary are added together.

To read more about how this all works, see the game page: https://celestial.itch.io/wireworld-1k

Viper 313

A top-down arcade shooter.

You start with three lives and regain lost lives every 750 points. Your ship has a shield that will absorb damage proportional to the shield strength. There is a boss fight every fifth stage. Some structures drop power-ups when destroyed. There are infinite stages.

Power ups:
Red: Gain Health
Blue: Gain Shield
Green: Invulnerability Shield
Yellow: Rapid Fire
Orange: Homing Missiles


A robotic mining operation on Ganymede has gone awry. The automatons deployed on the moon's surface is under the control of a hostile artificial intelligence. It is using the automatons to construct powerful weapons and ships in preparation for an attack on Earth. You pilot the Viper 313 craft remotely from an orbital station above the moon. Your mission is to destroy the structures and ships built by the evil robotic overlords.


Arrows moves your ship. O button fires. X button pauses the game.


Thanks goes out to the Pico-8 Team.

Cart #virulent-2 | 2021-03-13 | Code ▽ | Embed ▽ | License: CC4-BY-NC-SA

Virulent is a turn-based game where you use action points to manage a viral outbreak on earth. The story is that the earth is hit by asteroids carrying a deadly virus, your task is to launch missiles to prevent any more infections, while administering remedies to infected countries and cure them.

Virulent is a remake of an Atari game called "Epidemic!" by Steven Faber (1982). I hope you enjoy playing it.

I dedicate this game to every person who has been separated from their family or loved ones during the tragic corona virus outbreak of 2020. We miss you dearly.
