Jazz Jackrabbit 2: Holiday Hare '98
Jazz Jackrabbit 2: Holiday Hare ’98 was the first add-on for the game Jazz Jackrabbit 2, denoted by its version number, 1.23x. The game, unlike previous Holiday Hare installments, had to be purchased. This is also the only ‘add-on’ to not include a JCS. HH ’98 included three new single player levels created by Jon MacLellan, a new tileset (with a day, an evening version, and a night version), and three reskinned bad guys. The enemies are: Xmas Float Lizard, Xmas Lizard, and Xmas Turtle. The ‘add-on’ also includes a new piece of music composed by Alexander Brandon.
Jazz Jackrabbit 2: Holiday Hare ’98 was only released in the United States, but also formed the basis for the European add-on The Christmas Chronicles, which was basically Holiday Hare ’98 released with the 1.24 engine.
