Sig.NULL is a downloadable expansion to last year's Signal, a Sokoban-esque puzzle game about pushing blocks into place using drones that you control... more or less. The puzzles are hard enough as is, but discovering the bizarre mechanics that make everything run is another major endeavor. Even if you're familiar with how Signal worked, Sig.NULL adds many new features that make this a fresh challenge for all takers.
Signal is a Sokoban-esque puzzle game where figuring out what's going on is part of the fun. Your ultimate goal is to cover the targets with certain blocks, but the way blocks behave when you push them might surprise you. Take a moment and observe your surroundings when trying to decrypt the signals in this veritable brain-scratcher.
