Kronolog is a graphic adventure that is based in an alternate world in which the Nazis won the Second World War and subsequently enforced world domination. The world as it is now in a state of decay from excess pollution, environmental problems, and similar blights. Players take the part of Hoffman, a member of the government who is in search of his missing son.
The game uses a standard 2D-adventure interaction system. There are a series of icons that are clicked to achieve the desired action.
Kronlog features VGA graphics and includes a series of voiceovers and digitized pictures for specific conversations.
In the German Red Hell version of the game, the gameplay is the same, but the story arc has been changed significantly. The world is there conquered by Soviet Union instead of Nazi Germany. Instead of Nazism, the game has many references to Soviet culture. Even the main character is named "Mark Constantine" (a Russian surname) instead of "Mark Hoffman" (a German surname, from the original version) Other than that, everything is same.
