There are 8 different types of enemy:

• Static - blue - stand still, facing a single direction
• Moving - yellow - walk to the limit of their line, turn through 180 degrees, and walk back.
• Turning - teal - carry a knife, stand on one spot turning 180 degrees with each turn
• Pair - grey - two guards standing on one spot facing opposite directions
• Patrolling - green and red - have a set, rectangular route,
• Dog - static unless they see Agent 47 two steps ahead of him, when they will chase him indefinitely, until distracted by a noise or confused by a trapdoor
• High-alert - dark blue, carrying a flashlight - behave like yellow enemies, but the flashlight allows them to see the rank and file to their right, so long as it exists, and the view isn't obstructed
• Marks - red - static, and normally looking at the view instead of guarding.

There are 2 guns: a rifle, and Agent 47's classic dual silverballers. Guns can be used directly, by shooting an enemy, or indirectly, by shooting a statue, which can fall on an enemy, and will also change the board layout.

There are 6 additional game features:

• Trap doors - connect one location on the board with another,
• Potted plants - give Agent 47 a place to hide, allowing him to pass an enemy without killing them or being detected
• Statues - can sometimes be shot with a rifle to make them fall on an enemy, and render the path impassable
• Automatic walkways - push Agent 47, and enemies, to the end of their travel.
• Litter - can be thrown by Agent 47 to an adjacent vacant spot for attracting/distracting enemies
• Wait points - make Agent 47 wait on the spot one turn, for the purposes of putting you in sync with different enemies
