BackDoor

BACKDOOR

BackDoor is an in-development 2D network infiltration simulator set inside a fictional operating system called BD OS.

Use the terminal, inspect network maps, decrypt digital locks, copy mission files, manage your trace level, and complete contracts without being detected.

Everything in the game is fictional. BackDoor does not connect to real networks, websites, domains, IP addresses, or external utilities. The in-game browser and all .nest websites work completely offline.
