Ice Climber (アイスクライマー, Aisu Kuraimā?) is a vertical platform video game developed and published by Nintendo for the Nintendo Family Computer in Japan and the Nintendo Entertainment System in North America in 1985. In Ice Climber, the characters Popo (ポポ) and Nana (ナナ), collectively known as the Ice Climbers, venture up 32 ice-covered mountains to recover stolen vegetables from a giant condor. In some European countries, the NES console was sold bundled with the game, increasing Ice Climber's familiarity outside Japan. An alternate version was released in the arcades as part of the Vs. Series, known as Vs. Ice Climber (VSアイスクライマー, VS Aisu Kuraimā?). It includes gameplay features not found in the home console release, such as an animated title screen, stage select menu, 16 additional mountains, occasional blizzard and wind effects, more enemy characters, and bonus multiplier items.
