In HACK.BAK, the group F.I.S.H (Frivolous Information Sealing Hackers) have encrypted your precious data. They've left you the tools you need to find the key, but they're spread across a network of servers, routers, and other devices. Your job is to find the commands, traverse the network, and unlock your data.
Terminal-based Gameplay: Enter commands like you would in a linux terminal or windows command prompt. Supports tab-completion and command history.
Procedurally Generated: No two games are exactly alike. The order you'll find the commands and the layout of the network will change with each new game.
Network Size Options: Choose from a small, medium, or large game. The network map doubles in size with each increase.
Decryption Puzzle: Solve a bitmask puzzle to decrypt commands, but if puzzles aren't your thing, feel free to turn it off in the options.
Flexible Control Options: The game is fully controllable using just the keyboard, but that doesn't mean you have to. The game has controller support (native Xbox controller or Steam Input) as well as mouse support (with limited keyboard requirement).
All actions can be performed using the context menu via menu-key (or shift+F10), controller "Context Menu" binding, or mouse right-click.
Use your mouse, numpad directional, or controller joystick to navigate the network.
