Submachine 4Submachine 4Just received in my email box, from Mateusz Skutnik, the author of the famous Room Escape game Submachine series:

just wanted to let you know that there is a new chapter of the submachine available: Submachine 4: the Lab.

Submachine. The game in which with every puzzle solved, every chapter finished you fall deeper and deeper into mystery. Fourth chapter takes us to the heart of the submachine, the place where all questions will be finally answered. Or were finally answered. Once again it’s time to ask yourself – is it possible that you’re too late?”

Feel free to post your comments, and…

Have fun!

Note: complete walkthrough in comment #1!

Play Submachine 5 (walkthrough available) here!

    The game was fun. It killed some time. Chudson thanks for the secret tips. ??? the switches are for the square tiles in the ancient location match the design with the tiles to open them but only 1 at a time, and shawn 1st open the ladder to go up with the square and the round keys then go up 2 rooms and cut the rope with the knife so the tile drops and go all the way down to the bottom and collect it.

    I love these games! The second one is the best imo. It would be cool if they combined all these games and turned them into a movie with like some detective getting captured and having to find her way through all the mazes.
