Disney's Lilo & Stitch 2: Hämsterviel Havoc (titled Disney's Lilo & Stitch 2 in Europe and Disney's Lilo and Stitch in Japan) is a 2004 action-platform video game developed by Climax Studios and published by Disney Interactive Studios for the Game Boy Advance platform. A sequel to the 2002 Lilo & Stitch video game for the same platform developed by Digital Eclipse, Hämsterviel Havoc serves as the only tie-in video game for Lilo & Stitch: The Series.
While Disney's Lilo & Stitch 2: Hamsterviel Havoc is primarily a platformer, the player will have the chance to play as other characters and vehicle segments.
Play as both Stitch and Lilo to rescue Nani and David, who have been kidnapped by the evil Hämsterviel and taken onboard his spaceship. To complicate things, Hämsterviel created evil alien experiments that go head-to-head with our heroes. Start by capturing each Experiment and harnessing its special power in order to progress and capture the next. Sparky (Experiment 221) helps you out with his powerful electricity balls, while Richter (Experiment 513) shakes things up by igniting an earthquake. Gameplay modes include platform-shooting as Stitch, navigation, and strategy as Lilo, intense racing, and multiplayer mode.
- The Japanese title drops the "2" because the first GBA Lilo & Stitch game was not released in Japan.
