Glue

Glue is an option in Infiltrating the Airship during the "Government Supported Private Investigator" pathway.

Infiltrating the Airship
When chosen, Henry smears the glue over his hands, so he can climb up the wall of a room, and sneak over a Toppat Clan meeting. This results in a success.

Trivia

 * The option could possibly a reference to The Simpsons Movie, when Homer uses super glue to climb the Dome without getting spotted by EPA agents.
