About Bitburner

After 5 years of development, contributions from hundreds of developers, the critically acclaimed open source programming hacking sim is available on Steam.

Inspired by games like Else Heart.break(), Hacknet, Uplink, and Deus Ex, Bitburner is a programming-based idle incremental RPG where you, the player, take the role of an unknown hacker in a dark, dystopian world. The game provides a variety of mechanics and systems that can be changed through coding and solved or automated in whatever way you find suitable.

While a very basic programming background is recommended, it is not required to play the game!
  • Write scripts in JavaScript to automate your gameplay
  • Hack through a network of servers to train your abilities and earn money
  • Solve real programming questions to hone your skills and earn rewards
  • Improve your character with 100+ Augmentations
  • Trade in the stock market and write automated trading scripts
  • Interact with various gameplay mechanics to increase your stats and earn money
  • Explore the world and discover different companies, locations, and factions
  • Mini-games
  • Unlock secret perma-upgrades
  • Continuing development!
You can play the web version at https://bitburner-official.github.io/

Warning ! I only recommend this game if you like programming and upgrade-and-restart games !! You will need to write code to solve algorithmic challenges. You will have to write code to spread script execution inside a network. This is a good way to learn or remember javascript or typescript language. Notice though that the framework functions and libraries are adapted to the game and would not work in real life :) Please notice that some of the bash functions in the game have the same name as real life ones but do not work the same. For example [spoiler]there is a tail command that shows the log of a script instead of the code of the script[/spoiler]

For anyone interested in tech, cyber security, computers or want to learn what th dark part of cyber security is, I think it is a perfect game. I would recommend this game to anyone, it has a learning curve that may get to some, but once you learn the basics, it is a really fun game with programming, upgrade computers, buying servers, working jobs for money, and hacking servers to claim root access and running scripts on them to auto hack, weaken and grow. I have barely even scratched the surface of the game!. There are even mini-games and like a hundred achievements. Also, there are many guides and documentation in the game, and a massive community! If i were to mention every feature, I `would be here all day! Kudos to the developer!
