Scott Stilphen - Actionauts Impressions

October 2nd, 2007 by Scott Stilphen

Scott Stilphen is a classic gamer/archivist who has been active in the Classic Gaming community for many years. Recently Scott had a chance to spend a few minutes with the 2600 version of Actionauts.

“I had first caught a glimpse of Actionauts years ago at one of the Classic Gaming Expos, and remember thinking at the time that, for an unfinished game, it looked very close to being finished. A few weeks ago I had a chance to spend a few minutes talking with Rob about the game while he demonstrated it, after which he offered me a chance to play it! The game has an ‘action’ screen and the ‘programming’ screen, and both are rendered quite nicely and look very professional. The effect of alternating between both screens is particularly well done as the screen simply doesn’t alternate between the two but instead shows a nice transition, with the programming screen vertically sliding over the action screen (from the bottom). It’s an impressive effect that I don’t recall being used in a VCS game before.

The programming screen is especially neat, and immediately reminded me of those classic sci-fi computers, with their dozens of blinking lights. The game is rather challenging, even in its unfinished state. I would compare the gameplay to the classic Milton Bradley programmable tank toy, Big Trak. The program itself consists of a list of icons that you can change (via the joystick). The action screen I saw showed a simple maze (for level 1. Perhaps subsequent level mazes are more intricate…).

Besides some of the obvious commands (go forward, turn left, right, etc.) there were a few that Rob mentioned were never fully realized (i.e. you can fire and jump, but there’s nothing to jump or shoot at). Not having a feel for how far the robot travels with each command, I had him into a wall in no time :) Alas, my turn ended before I could create a successful program and get the robotic “mouse” to the cheese.

As prototypes go, this one is quite playable and I didn’t notice any graphics glitches or bugs. It’s unfortunate that it was never completed as I could immediately see the potential in having 2 players in head-to-head competition, jumping and firing as they scrambled to reach the goal first. Sounds effects were also minimal (or missing altogether?). Nevertheless, I look forward to spending more time with it upon its release.”

Actionauts - my last Atari 2600 game

October 1st, 2007 by Rob

Spring, 1984. The videogame business was taking a severe nosedive. Leaving Imagic had been difficult for me. I missed the infrastructure of the organization I had been a founding member of. I missed the security of a regular paycheck, as well as the quarterly royalties from Demon Attack, Cosmic Ark, and Fathom. Most of all, I missed my colleagues, some of whom I had worked side-by-side with since I started at Atari. It was hard for me to accept that Imagic was gone. I didn’t really understand what had happened. We had all worked hard, we had done some great games that enjoyed a lot of market success, we were in all the game magazines. The creeping thought that “videogames are really over” was not a possibility I was prepared to accept. Not yet.


I had my mind made up to make a game on my own. It would be so easy … a piece of cake. I purchased a Kontron development system, a 6502 compiler, and some office equipment, and had everything delivered to a little office I had rented a few miles from my Palo Alto apartment. I even had a vague notion of a game that I thought was a “natural” at the time.

The early 1980s had featured the introduction of several low cost home computers. “Programming” was all the rage in high schools. Technology ‘bandits’ known as “Hackers” were becoming cultural icons. And in the world of stuff for kids, robots had essentially taken over popular culture. Robots were EVERYWHERE. I’d walk into a newstand, robots were on the cover of major magazines. I’d turn on the TV on Saturday morning, most of the shows featured armies of robots forever battling, speaking in deep mech like voices. Toys R Us morphed into Transformers R’ Us. Many robots came from Japan, the hippest ones of all still featuring their original Kanji packaging, which instantly branded the contents as obviously MUCH cooler since it was Japanese.


I set out to make a game featuring a programmable robot. Such occured to me at the time as a “natural”. My goal was to create a simple and fun programming game, with the principal challenge consisting of the experience of “debugging” - doing the basic “how did I blow it THIS time” shuffle .. a familiar dance near and dear to the heart on anybody whose written even the simplest BASIC program.

The idea was pretty basic. A robot on the screen would be controlled by a linear series of ‘commands’, it’s program if you will. There would be four commands to start with … consisting of the most primitive things a robot could be told to do. The player needed to get the robot to acheive a number of onscreen objectives.


Actionauts (the early working name was “Microbots”) consists of two screens. The main play screen features a single robot in a simple playfield maze, a “target”, in this case a piece of cheese, and a vertically scrolling command display at the bottom of the screen. Every time a command rolls off the screen, the robot ‘executes’ that command. Player control in this mode is limited to setting the speed of the system, indicated at the bottom right, and starting/stopping the robot’s execution of it’s commands. The object of the game is to create the proper sequence of instructions so that the Robot reaches the cheese.



Obviously the Robot won’t always get to the cheese, due to faulty ‘logic’ on the part of the player. When the robot crashes and can no longer make any progress, the player can switch to the “program editor”, where they have control over the sequence of commands the robot will execute when it next ‘runs’.

Switiching modes causes the program screen to segue front and center (I was especially proud of the seamless segue effect which helped keep continuity as to “where” the player was in relation to the two screens.

On the programming screen, users scroll a blinking cursor up and down through the various commands, with left/right joystick used to scroll through the four possible commands for each ‘link’ in the chain. When the player thinks the sequence is “ready” … a quick tap of the joystick returns to the Main Screen, where the robot runs through the program again.



The play challenge in the game comes primarily from “debugging” .. with the player needing to remember what the robot last did, what went wrong, and find /fix the appropriate command (s). There are nine playfields in the game.

By June, 1984 it become pretty clear that there was no longer any sort of viable market for Stella games. At that time, Actionauts was basically in it’s current state. The program editor screen was there, the interface reasonably smooth, and pretty easy to get around. The Main Screen was functional, yet not “polished” in terms of visual appeal. I had planned a more robotic looking central character, and the cheese was just a cardboard ‘prop’ simply to get the game functional. also had always intended a secondary character, primarily to serve as ‘conflict’ in later levels. I also was planning to add a significant number of additional levels beyond the nine that now exist. In terms of development, I consider Actionauts about 1/2 way completed.

People ask why the back end of the game is solid, while the front end is not as polished. Such is because I was then, and still am today, a firm believer in building games “backwards” In other words, I get the game up and going as soon as possible, typically crafting the first level to be as hard as I think it should be. Then I build backwards from the hardest level. This way, the first level of the game, which is the one that the player will see right away, is only undertaken when I know as MUCH as possible about the contents of the game itself. Also, by the end, I’m about as good as I’m ever are going to get at crafting levels for this particular game, which is important because it’s the early levels that get the most play. A lot of designers build their games front-to-back, so that the first levels the player encountered, are also the first levels the designer had built. Night Driver was the only game I did front to back. And such is why Night Driver has a gawd awful ramp in terms of moving the player through a learning curve. And that’s why Actionauts isn’t as polished when one first fires it up … I started at the end, with the programming part … and never got to the ‘beginning’ since there was not a lot for the player to do on the main screen but watch his little robot do it’s thing.

It wasn’t an easy decision to abandon Actionauts when I did … it was going to the last CES in June of that year that sealed the coffin shut. I eventually put a lot of the ideas that came out of Actionauts into a more sophisticated version for the Commodore 64.

But that’s a story for another day.
