HOW or Human Operations Worldwide is a full version adventure game developed by LXXII for Windows. The game is set in a building filled with massive death machines and fast, ugly creatures that chase the player through the halls. The objective of the game is to survive and escape by using strategy and survival skills.

The game does not have a set path for the player's story and requires exploration and scavenging to find keys and progress through the seven levels accessible by elevator. Each level presents new challenges and monsters to hunt you down. The player must also collect batteries to supply their flashlight needed for exploring the dark maze-like building.

Overall, HOW is a punishing and terrifying experience that requires quick thinking and strategic planning. It's a great game for adventure and horror game enthusiasts who are looking for a challenging and immersive gaming experience.
