Disney's Lilo & Stitch 2: Hamsterviel Havoc for the Game Boy Advance is a vibrant action-platformer and the only video game tie-in for Lilo & Stitch: The Series. Developed by Climax Studios, this sequel expands on the original's "run-and-gun" gameplay by introducing new strategy elements and the ability to harness the powers of Stitch's captured experiment cousins. 
 
Key Features
Dynamic Duo Gameplay: Take control of both Lilo and Stitch to rescue Nani and David from the nefarious Dr. Hämsterviel’s spaceship.
Action & Strategy Modes:
Stitch's Levels: Fast-paced, Metal Slug-style platform shooting with 8-directional aiming and double jumps.
Lilo's Levels: Wits-based navigation and strategy puzzles where you call on captured experiments to reach difficult areas.
Harness Experiment Powers: Collect and "borrow" unique abilities from Jumba’s other experiments to overcome obstacles. Examples include using Sparky (221) for electricity or Richter (513) to trigger screen-shaking earthquakes.
Varied Mission Types: Experience 29 levels across three distinct play modes: traditional platform shooting, strategy-puzzles, and intense racing segments.
"Experiment Ball" Collection: Hunt for hidden experiment balls—symbolized by stars and clovers—to free Stitch's cousins and recruit them for future missions.
