This game came out last year and was programmed by Ed Fries,who was once Vice president of Microsoft game publishing division.
Fries has been in the gaming industry for over 20 years and he also programmed games for the Atari 800 back in the day.
The game itself is a technical accomplishment, especially when you consider he only had 4k to work with.
Gameplay wise you have to control Master Chief through 64 rooms And and avoid or shoot a number of baddies and you even get face a boss, in a final battle, but that’s not all before you do any of that you have to locate your gun and also find keys that open energy barriers.
The game was released in limited addition Atari 2600 cartridges but it can also be download for free and even chat to Ed Fries @
