    Optional Puzzle 6 - Sector F56 - [6:59]
    This puzzle requires some basic knowledge of boolean logic gates, and how they work. The symbols can be found below:

    Legend:
    V - Or
    ∧ - And
    ⊕ - Either or (but not both)
    ¬ - Negation (true if condition is false)

    Grouping is very important here. 8 slots have 4 pairs. 4 pairs make 2 halves. Both halves are joined to create the answer and decide the outcome (True or False). Make sure you are solving each individual pair, and then work into halves and the whole.

    You can solve the conditions of each room to make the entire gate true or use the video to the quick solutions to each room and some explanations of how the mechanics work.

    Lord NazuleThanks Knoell.

    If it doesn’t pop completely shut down game and replay. It popped for me.

    DrewYeah I had an issue with this achievement popping as well; tried signing out but it wasn’t doing the trick. Once I shut down the game and tried the puzzle again, the achievement unlocked. Must be bugged

    For anyone who wants the answer without watching a minutes-long video, here's the solution:

    O = Orb
    X = Empty

    Gate 1: X X X X X X X O
    Gate 2: O O O O O O O O
    Gate 3: X X X X X O X X
    Gate 4: X O O O X O O O
    Gate 5: O X O X O X X O
    Gate 6: X O X O X O X O
    Gate 7: X O X O X O X O
    Gate 8 (After going through the grid, and getting more blue balls): O X X O X O O X

    MathGuy42Nice fast solution.

    A couple comments, gleaned from the Walkthrough: If you have any energy balls in your gun, you can't go through a force field after Gate 7. Maybe your solution uses up all balls for Gates 1-7, but I had one extra by solving my own way. I had to discard it.

    Also, for those solving on their own, Gate 7 has Not symbols that are hard to notice.

    CurtiesonI don't know if something changed...but it felt like the final 4 were all just every other (or one of the pair), again and again. That is BASICALLY what you have anyway, minus 5 and 8.
