Zombie Army 4 Death Canal – The Shadows of Venice Lights Puzzle
In the video above, you can see the solution. This puzzle comes right at the end of the level, just before you go into the safe room. As you enter the room this puzzle is in, on the wall to your left is scrawled;
Use your BRAINS BRAINS BRAINS BRAINS
On the right wall are three rows of hanging coloured lights and the alphabet. Each letter is above or below one of the coloured lights. In the right-hand corner is a locked safe.
To open the safe, shoot the lights corresponding to the word “BRAINS.” If done correctly it will unlock the safe. Be careful if you have explosive mods/upgrades as you will likely break more than the intended globe and will be unable to unlock the safe.
