Jetpack

Jetpack is an item Henry can choose in Escaping the Prison and Completing the Mission.

Escaping the Prison
Henry tries to get off the Prison roof with a jetpack. When he turns it on, it starts up and stalls. A very long fail screen appears for a second, before the jetpack suddenly turns on and flies all over the place. Henry ends up crashing into the West Mesa Penitentiary wall, right back in his cell, and possibly dies as he breaks the concrete wall. This is where Repairman spots him and casually says: "Oh look, you're back."

Fail Message #1
Wow... That was the lamest thing I've ever seen. The animator must have gotten REALLY lazy or something. I mean honestly that was probably the dumbest FAIL I've seen in this entire game*! So anyway, what do you think of the game* so far? Enjoying it? It's been quite a while, and as I'm typing this it has yet to be completed. I doubt you'll be able to read this far down unless you figure out a way to pause or do some other sneaky thing. Laaaammmeee!

* - "movie" in legacy version

Fail Message #2
It takes many hours of jetpack training before you're able to operate one.

Trivia

 * This is the only item/option in the entire series that triggers two fail screens.

Completing the Mission
At the start of Triple Threat, Henry and Ellie Rose can use the jetpacks to get from the helicopter to the Toppat Launch Site. They crash into a turret and destroy it but survive the crash and can continue their mission. Ellie will comment "That was... weirdly... smooth."
