Halpha Environmental Testing Zone Survey/Strategy/Puzzle sectors

Some sectors contain puzzles where you must press certain switches using information based on your surroundings.

Nonogram/Picross type

These puzzles primarily generate on corner sectors. Players step on floor switches to solve a Nonogram (also known as Picross) puzzle to unlock the crates. If a wrong switch is pressed, a nearby lever can reset the puzzle.

All switches immediately lock and disable upon puzzle being solved.

Puzzles range from 4x4 to 5x5 grids. For a list of puzzles, click here.

Path Drawing type

Puzzles with multiple switches along a wall, representing a light path. The goal is to press them in a specific order to connect the trail from the starting point to the ending point.
