Negentropy vs BUNKER PROTOCOL

Step inside and wander the halls of a house of old. Play through a set of puzzles in each room to move ahead. Take the letters out of a state of entropy, strategically putting them together to make four different words! Can you make your way to the next room?

You wake up alone in an abandoned military black site. The command terminal is dark. The security door is sealed. Your only way out is to solve every puzzle left behind in this classified facility.
