What is MINDNIGHT?

This free-to-play multiplayer deduction game takes place in cyberpunk San Francisco in 2038, where cities have shut down the open internet. In matches for five to eight players, you receive an Agent or Hacker role and use discussion and deception to secure or hack three of five network nodes. Hackers know their teammates, while Agents know only their own role.
