Submachine 6: The Edge

The Submachine series consists of ten games which develop the main storyline and four spin-offs. In the games the player explores a mysterious world full of collapsed structures and strange devices and has to find a way further or out. Submachine 6: The Edge begins at the moment Submachine 5: The Root ended: the player is travelling in a "mover", but the machine is intercepted and he or she is dropped off at some deserted cliffs. From there the player has to get inside, access the submachine defense system and turn it off. Therefore many tasks are performed in cyberspace, but it's represented mostly as a series of simple visual logic puzzles.

The game develops the story much further. The player finds some messages from a predecessor (as always, we never meet him, but we can presume from one of the messages that he is dead anyway) and this way faces important questions: Is Murtaugh evil? Should we help him, or perhaps switch sides and find someone else to guide us through the submachine network?

The 2009 browser version of the game is free. The 2013 HD version for PC is a commercial release.
