Infiltrating The Airship

What is Infiltrating the Airship?

Infiltrating the Airship is the fourth entry in the beloved Henry Stickmin series, a set of choice-based browser games that combine the format of a choose-your-own-adventure with rapid-fire slapstick comedy. Henry Stickmin has been tasked with infiltrating a massive airship belonging to the Toppat Clan - a criminal organisation whose zeppelin serves as their mobile headquarters. The game presents you with a series of decision points where you choose how Henry attempts each obstacle. Some choices succeed and advance the story. Most choices fail in spectacular, creative, and genuinely funny ways. The fail states are often more entertaining than the successes, which is what makes replaying worthwhile.

How to Play Infiltrating the Airship

At each decision point, you're presented with a panel showing the current situation and a selection of items or approaches to choose from. Click the option you want Henry to attempt. If it works, you move forward in the story. If it fails - which is most of the time on your first playthrough - you get a brief animated failure sequence that plays out the absurd consequences of your choice before presenting you with the option to retry or continue. The game has multiple routes through it depending on which key decisions you get right, and some paths branch significantly from others. Completing all routes and uncovering all fail states is the real replay objective.

The Henry Stickmin Humour Style

The writing and animation in Infiltrating the Airship represent the Henry Stickmin series at peak form. The humour draws heavily on pop culture references, with fail states that parody specific games, films, and memes in ways that reward players who recognise the sources. The animation style is deceptively simple - the stickman characters have limited detail but excellent comedic timing, and the voice-acted exclamations from Henry and his enemies land consistently. The game doesn't talk down to its audience or explain the jokes; it trusts you to either get the reference or simply enjoy the physical comedy of yet another spectacularly wrong tool choice.

Multiple Routes and Endings

Infiltrating the Airship features several distinct routes through the aircraft, each with a different approach to the infiltration - sneaking through vents, posing as a guard, direct confrontation, or more creative methods that it would be a shame to spoil. Each route has its own set of decision points and fail states, and they diverge early enough that replaying to see a different route genuinely feels like a different experience rather than minor variations on the same path. The game also tracks your completion, letting you see how many fail states and endings you've found versus how many exist - which gives you a clear target for completionists.

Fail States as Entertainment

One of the Henry Stickmin series' most clever design decisions is making the fail states as entertaining as the successes. In most games, failing a decision means wasting time. In Infiltrating the Airship, making the wrong choice triggers a short animated sequence that is often funnier and more memorable than anything in the correct path. Some players deliberately choose wrong answers first specifically to see all the failure animations before finding the correct one. This turns what could be a frustrating trial-and-error loop into an actively enjoyable process of discovery. The game is generous with its comedy; it wants you to see as much of it as possible.

What Makes the Stickmin Series Special

The Henry Stickmin series occupies a unique position in browser gaming history. Developed entirely by Marcus Thiesen as a solo passion project, the games grew from simple Flash experiments into genuinely polished, lovingly crafted comedy adventures. By Infiltrating the Airship, the series had developed a consistent voice, a recurring cast of characters, and a tone that felt entirely its own. The games were later remastered and collected into The Henry Stickmin Collection on Steam, a release that introduced them to a new generation and gave the original creator commercial recognition for work that had previously been entirely free. The browser originals retain their charm completely.

Perfect for Short Sessions

Infiltrating the Airship is well-suited to school gaming sessions because it doesn't require continuous attention across a long play window. You can pick it up, work through a few decision points, laugh at a handful of fail states, and put it down without losing meaningful progress. Each run through a route takes ten to twenty minutes for a first-time player and much less once you know the correct choices. The comedy is immediate and self-contained within each interaction rather than building slowly across a long narrative, making it accessible regardless of how much time you have available.
