Completing the Mission is planned to be AROUND 3 times bigger than Fleeing the Complex. That's a lot of paths! Yep, that's what happens when every ending is canon! Also, don't worry, a lot of your favorite characters will definitely be making a return. This includes Ellie, and Charles, as well as many others!
PuffballsUnited announcing the game[src]

Completing the Mission is the sixth and final game in the Henry Stickmin series. It released alongside The Henry Stickmin Collection on Steam on August 7th, 2020.

Unlike the other games in the series, Completing the Mission is exclusive to The Henry Stickmin Collection and is the only game in the series to not be released on Stickpage or Newgrounds.


The game takes place after the events of Fleeing the Complex.

However, unlike the previous five games, which had one main story with different possible endings, Completing the Mission contains multiple possible stories. Which story/mission the player gets depends on a choice made at the start of the game which endings from Infiltrating the Airship and Fleeing the Complex the player wishes to continue from.

The only thing the missions have in common is that they all involve (the remains of) The Toppat Clan making one final move. In most missions, they have a new Orbital Station, which they either are about to launch from the Toppat Launch Site in the Dogobogo Jungle (with the military trying to prevent the launch in The Toppat Raid) or have already launched and are now operating from Space. Some endings take place almost entirely on the Airship.

Henry's motives in the game change drastically, also based on the combinations of endings that the player chooses. Henry will want to launch the rocket if he's sided with the Toppat Clan, stop it if he's working for the government, or break into it for the riches of the Toppat.

Note: Since the complete Gameplay of the game is too big to be shown in the same page, you are requested to refer to the Ending's pages in order to visit their Gameplay.


After the events of Fleeing the Complex, the Toppat Clan is getting ready to launch their rocket into space to establish their orbital station.

Various scenarios will turn out from the different endings of Infiltrating the Airship and Fleeing the Complex, such as:

Paths and endings

Overall, there are 15 different paths the player can create by combining endings from Airship and Complex, and 16 endings; the combination Pure Blooded Thief/Convict Allies being the only path that leads to two different endings depending on the final choice made. It also is one of the two forks at the Final Selection of a game, the other being(Storage Bay: Captive)

Note: The Ending Multiverse Correction was also one of the two forks in the game, but since it does not count as an actual ending in game, it is not considered to be a fork.

It should be noted however that not all endings from the two previous games can be combined since some are incompatible. Picking "Rapidly Promoted Executive" and siding with the Toppat clan in Airship prevents the player from selecting "International Rescue Operative" and getting help from Charles due to Henry betraying the Government. Similarly, Picking the Ending "International Rescue Operative" will prevent the player from selecting the "Rapidly Promoted Executive" ending.

  • Choosing any endings with reference to either Faction (The Government of the Toppat Clan) will remove selecting single/Multiple endings from the other game, respectively.

The endings are:


The bios have the names of 222 individual characters appearing in this game (by far the, largest amount in a game).


Main article: Completing the Mission achievements

There are 27 medals in the game. 3 of them are secret. 16 of them are the endings. The Main article of them is above. A lot of them are the endings. There is one medal that is classified as not an ending, but could definitely be one. (It's one of the secret ones.) See more at this page.


  • This is the only episode where the Game Over text is "Mission Failed" instead of the usual text, "FAIL".

Development Timeline

Series' creator PuffballsUnited announced the sixth installment to the Henry Stickmin series on November 22, 2016, on Newgrounds, revealing that the game will be "huge" and will take more than one year to come out. He also said that Ellie will return as a character.

On January 4, 2017, Puffballs United officially announced that he started working on the sixth game. He said that the game will maybe be the final installment in the Henry Stickmin series and that it will be at least "3 times bigger than Fleeing the Complex". Unlike all the other games in the series, the sixth game will not be a free online Flash game, and that it would instead be released on Steam along with remastered versions of all the other Henry Stickmin games as part of The Henry Stickmin Collection.

On December 12th, 2017, Puffballs United revealed part of an image that would later be fully revealed on January 3rd, 2018. The same day, the acronym for the game was revealed to be CtM.

On May 22, 2018, in a new Newgrounds update, PuffballsUnited revealed the full title of the game: Completing the Mission. He also confirmed that Charles and "other loved characters" will be making a return. On December 30th, 2018 a brief update was released, stating that the game was at 25% completion and showing a sneak peek of an updated Center for Chaos Containment logo, confirming its appearance in the game.

On February 15th, 2019, a teaser was posted in Newgrounds, showing the game's path customization. Sometime after, Puffballs United livestreamed work on one of the fails in the game on Twitch. In this stream, Ellie, the Toppat Clan, guards from The Wall, and the Government are shown, officially confirming their return. The fail in question consisted of Henry tying a rope to a Rocket Launcher's trigger, Ellie throwing it in the air, and him pulling the trigger from the ground to fire it. While this would've let them fire the Rocket Launcher from a safe position, the Rocket Launcher was pointing down towards them the moment it was fired, so they only managed to hit themselves with the rocket.

On July 5th, 2019, PuffballsUnited made a new post on Newgrounds expressing that the game had hit 50% completion. Additionally, a new teaser was shown and the Steam page for the Collection was launched, also containing a few new images. Finally, he reveals that a summer 2020 release is planned.

On January 1st, 2020, PuffballsUnited did a New Year's update of the game. In this, the setting was officially confirmed to be a Toppat Clan base, and few new teasers were shown, including one on path customization, which showed that some path combinations won't be possible.

On April 1st, 2020, a short video of the game was posted on his Twitter account, showing, allegedly, a fail of the game with Charles involved and a joke update of the game. In this video, Charles tells Henry via an earpiece that he will fire a subsonic wave into the base, which "should stun everyone that hears it", and that Henry "may want to cover his ears". The subsonic wave kills everyone present, including Henry, although Charles is unaware of that.

On June 19th, 2020, Puffballs announced a release date of August 7, 2020 on both Twitter and Steam.

On June 30th, 2020, Puffballs announced that Completing the Mission's animation was 'basically done', and that the game would have 16 endings and 164 total fails.

On July 15th, 2020, Puffballs released the logo for Completing the Mission, its menu screen and the name of the secret Toppat base, the Toppat Launch Site.

On August 6th, 2020, Puffballs released a launch trailer for Completing the Mission, a day before the launch of the game.

On August 7th, 2020 (9:00 AM PDT), The Henry Stickmin Collection released on Steam.
