Commander Keen Is At It Again! is a Keen 1 levelpack by transporthummel, with 24 levels plus some modified graphics and a new story. It was made for the author's kids. The first half of the levelpack is comprised of linear level design with no Rayguns nor a pogo, while the second half is a bit more open and non-linear with some Rayguns. The pogo is collected about midway into the levelpack to progress through a certain level (that is otherwise only exited via a teleporter). There are some inventive parts, such as skydiving with lots of Gargs.


As stated in the in-game story section:

Billy Blaze, the eight year-old genius only known to the universe as COMMANDER KEEN, DEFENDER OF EARTH is at it again! It's a boring Sunday afternoon, all his friends are on vacation, and there's nothing good on TV. Crusing through the vastness of space in his good old Bean-with-Bacon Megarocket to kill some time, our hero suddenly gets sucked into a wormhole. The next thing he knows, he's crash-landed on an unknown purple planet.

As he steps out of his damaged spaceship, Keen quickly realizes that he's not alone on this strange new world. He knows he'll once again have to fight his way through a planet full of hidden secrets and dangers to survive and find his way back home to Earth...


Besides the Vorticon Guard, all actors remain unchanged.


In addition to most of the Keen 1 items, there is a new secret point item. Only the ship parts are replaced, by a trophy that is invisible until collected.
