The original game, Frost Bite, was among the first of Nitrome's works. It was the eighth game, released in 2006. It followed the adventures of the Climber as she climbed a set of mountains. Using the mouse, the player can control the climber to scale platforms, defeat enemies, grab on to holds, and more.
Frost Bite 2 was the direct sequel to Frost Bite, released in 2008. The player once again was required to climb a set of mountains, with no apparent plot.
Thin Ice is widely considered to be a spin off of the main Frost Bite series, as it contains the Climber and other characters from the series. The player must skate holes around enemies on a thin frozen lake, causing them to fall in. This game is widely similar to the Intellivision game of the same name.
