This run plays through all four "missions" (episodes) back-to-back, as playing through the first three missions is required to unlock the fourth mission.

The protagonist must traverse a 30-story building and deliver the pizza within 30 minutes. Colorful rabbits armed with booby traps, phone bombs, rocket launchers and bomber planes that drop water balloons seek to prevent the delivery.

Partners in crime turska & Ilari deliver the pizza in a record-breaking 03:33.52, or 7:42.00 according to the ingame clock. For details on how they did it, read the authors' commentary.

You move around with the arrow keys. If you manage to find a weapon, you can attack enemies by simply moving into them. Similarily, you can pick up objects on the ground by moving into them. You can also type in commands such as "LOOK DESK", "TAKE KEY", "READ BOOK", and "DROP FLASK". There are treasures to be found and monsters to be slain in order to increase your score.

In this TAS, Ilari & Truncated clear the game in a blindingly fast 19.45 seconds utilizing subframe optimization and rapid keyboard-twisting input. For details, read the authors' comments.

The run is so fast that the emulator can't draw all of the game's video output, so the downloadable encodes are made with a hacked version of the emulator that draws all of them.

In this run, the author takes back what is Keen's without firing shots at any organic lifeform. Reading the author's comments is recommended.

Here the author beats back the Vorticon invasion in slightly under 5 minutes, leaving one to wonder why we here on Earth bother with military defense at all. It's not quite that easy though; reading the author's comments is recommended to understand the planning and manipulation required for Keen to waltz by Vorticon after Vorticon.

If you enjoy this movie, check out these other Commander Keen TASes, all by the same author.

Several months after the freeing the Vorticons from Mortimer McMire, Commander Keen (Billy Blaze) finds out that an unknown race called the Shikadi are planning to destroy the Milky Way. He sets course towards Gnosticus IV on a quest to discover their location with the Oracle's aid. Upon arrival, he discovers that the Shikadi have captured the Council Members. In order to save the universe, Keen must fly to the Shadowlands and rescue them.

Using a series of tricks listed in the submission text, Keen reaches the ending in a mere 10 minutes.

Be sure to also watch the exciting conclusion to Goodbye Galaxy.

Using a series of glitches, Keen completes only four stages to get to the end game, only one of which takes any significant length of time, and destroys the Quantum Explosion Dynamo, the core of the Omegamatic in the impossibly short time of 2:02. In the process, he manages to inadvertently prevent the Shikadi from accomplishing their escape (though you have to watch the ending very closely to figure out that this has happened here).

Commander Keen 6 is also the third Keen game to get absolutely destroyed at TASVideos. Watch as Keen goes over, around, or through everything in his way to beat the entire game in a bit over three minutes. Reading the author's comments is recommended, and probably mandatory if you want to know what happened.

Before playing the movie, no matter the format, it is suggested to lower the volume of your speakers, headphones or earphones, since this game has loud sound effects!

Here, veteran DOS TASer Ilari uses tricks requiring exacting precision to squeeze every last millisecond out of this 6 level game.

This game runs too fast on anything more modern than low-end 386 or so. As such, the encode is technically correct. There is an encode on Youtube that slows it down to 30fps.

This version of the run is 2.65 seconds faster than the first.

Here, you can feel vindicated that you don't have to play through those tracks yourself.

The author, c-square, completes this game using major sequence breaks that are almost impossible to perform unassisted without abusing saves. To help with this TAS, the source code of JPC-rr was modified to support mouse input fully. See the submission text for details.

This run by Vampier makes one full round around Antarctica and finishes in just under 14 minutes.

This is an improvement of 37.88 seconds over the previous run, courtesy of better boss fights and other general optimisation.

Here, Quibus showcases precise blasting on the first two stages and a perfect score on the first bonus stage.

The authors, zggzdydp and scrimpeh, run through the game at breakneck pace, taking much more damage than they should be able to.

Unfortunately, saving the princess takes more than just successful recovery of the fruit and raw speed, so this run gets the bad ending.

Reality is not all it seems, with spiders being as difficult to kill with a knife as a human, and foodlike substances adopting an alternate name.

However, since every stage is identical, Quibus just plays through stage 1 as fast as possible.

The player uses these emotions and each of the characters' powers to find the four pieces of Uşas' jewels as fast as possible.

To play the OMR file, you have to have the Panasonic FS-A1WSX bios installed.

This version is different in some important ways. For instance, you must collect a white key in each stage to advance to the next stage. The chain whip is lost after each boss battle. Some subweapons can be bought from sitting bystanders in white or red clothes.

This is an improvement of 29.03 over the original run thanks to a few new time-saving tricks.

In addition to the normal encode, an experimental WebM encode is available for download. Feedback would be appreciated.

The program used to make this run, Hourglass, was also developed by nitsuja—with the creation of this run in mind. As such, it is our first published run of a Windows game.

Despite not collecting all the gems, this run by Bernka achieves the good ending by using a glitch to trick the game into unlocking Level 8 with minimum gems.
