Hidden Dimensions 3

Hidden Dimensions 3 (or HD3 for short) is a science-fiction themed collectible cards game offering nearly 500 cards and varied gameplay modes and challenges.

Control a powerful baseship capable of launching ships, deploying structures and performing actions. The structures provide various support roles and are the backbone of your fleet, generating energy required to launch larger ships. Ships serve to both defend your base against the fleet of your opponent, and to attack the opposing baseship.


  • almost 500 cards to collect
  • duel against the AI, and control the difficulty and gameplay rules in great detail
  • build your own decks, or let the game create them for you
  • participate in challenging events
  • a customizable flagship to lead your fleet into battle
  • combat boosts that provide varied benefits during battle
  • countless mercenaries that can assist you in duelling your opponents
  • major gameplay modes : unpredictable, mercenary bosses (and more coming in the future)

Game status

HD3 for windows is currently in open beta ( download locations here : Nulll-void.com ). Clients for Linux, Mac and Android are available, but these are still in alpha testing. An in-game savegame backup system exists, allowing players to transfer their progress between all platforms.
