The Commander Keen series of games follows the adventures of a boy, called Commander Keen, and his battles with the evil Vorticon aliens.
The series was a project that John Carmack worked on before Doom and Quake and was one of the first PC games to have smooth sideways scrolling.
This is the fourth game in the series, boasting better graphics and larger maps.
A complete history of the Commander Keen series can be found on Wikipedia.
As this game was first written for DOS, we recommend downloading and installing DOSBox to play it. Commander Keen 4 works fairly well with the default DOSBox settings but you may also want to install D-Fend to save any specific settings.
